Key Takeaways

• ACMA is increasing pressure on offshore casinos through website blocking, investigations and action against illegal gambling services.
• Offshore operators are adapting by changing domains, using multiple brands and relying on distributed marketing and affiliate networks.
• Website blocking has limits because blocking one URL does not necessarily remove the underlying gambling business.
• Affiliate websites are an important enforcement challenge, as they can promote offshore gambling services independently of the casino’s main website.
• Offshore jurisdiction remains a major regulatory weakness, making direct enforcement against overseas operators more difficult.
• Payment, hosting and software providers are increasingly important because regulators can disrupt the infrastructure supporting illegal gambling.
• VPNs and other access technologies create additional challenges, although technical access does not make an offshore casino legal for Australian customers.
• Consumer protection is a key concern because offshore services may not provide the same protections available through Australia’s regulated gambling framework.
• ACMA enforcement is shifting from individual websites toward the wider ecosystem, including advertising, affiliates, platforms and service providers.
• The main regulatory challenge is domain and operator resilience: blocking websites can disrupt access, but eliminating the underlying offshore business is considerably harder.
• Future reforms are likely to increase pressure on offshore operators, particularly through stronger controls on gambling advertising and inducements.
• For Australian players, accessibility does not equal legality: an offshore casino being available online does not mean it is licensed or authorised to provide gambling services in Australia.

How ACMA Is Changing the Offshore Casino Market in Australia

Australia has one of the more tightly controlled online gambling environments in the world. For Australian players, online casino gambling sits in a very different regulatory category from licensed sports betting. Online casino-style services, including online slots, roulette and blackjack, are prohibited from being provided to Australian customers under the Interactive Gambling Act.

Despite this, offshore casino websites continue to target Australian consumers. The result is a continuing contest between regulators attempting to disrupt illegal operators and offshore businesses attempting to maintain visibility, customer acquisition and commercial access to the Australian market.

The important point is that this is no longer simply a question of blocking individual casino websites. The modern offshore gambling market is an interconnected ecosystem involving operators, domains, affiliates, advertising channels, payment providers, software companies, hosting businesses and digital platforms.

Understanding that ecosystem helps explain both how offshore casinos adapt to Australian regulation and where the current regulatory model faces limitations.

The Australian offshore casino market

The Australian online gambling market is unusual because consumers have widespread access to regulated online wagering while online casino services are prohibited.

This creates a clear distinction between Australian-licensed wagering services and offshore casino operators.

A player searching for online casino games may encounter websites presenting themselves as Australian-friendly casinos, international gambling platforms or specialist online gaming brands. Some use Australian terminology, currency references, familiar payment methods or locally oriented marketing to make the service appear relevant to Australian consumers.

However, an Australian appearance does not mean that a casino is licensed to operate in Australia.

This distinction is central to understanding the offshore casino market. Many offshore operators are located outside Australian jurisdiction, which makes direct enforcement considerably more complicated.

ACMA therefore relies heavily on disruption rather than conventional licensing enforcement.

Website blocking, investigations, formal warnings, referrals to hosting and domain providers, action against affiliate websites and cooperation with digital platforms have become important parts of the regulatory strategy.

The scale of the activity is significant. During the April to June 2026 quarter, ACMA reported investigations involving 76 gambling sites, 56 identified breaches and 187 URLs referred for blocking. The regulator also reported that most of the websites targeted through blocking were casino-style services.

This demonstrates an important characteristic of the market: blocking one website does not necessarily eliminate the underlying business.

Mirror websites and changing domains

One of the most obvious adaptations by offshore operators is the use of alternative domains.

A casino website can disappear from one domain while the underlying business continues operating elsewhere. In some cases, an operator may establish additional websites or replacement domains following enforcement action.

This creates a basic problem for domain-level regulation.

A website block is highly effective against the specific address that has been blocked. It is less definitive when the business can establish another digital identity.

ACMA has explicitly identified alternate websites established to evade previous blocking action. This means domain churn is not merely theoretical; it is an established feature of the illegal online gambling environment.

From a regulatory perspective, this creates an asymmetry.

The regulator has to identify a service, establish that it breaches Australian law, process enforcement action and communicate blocking requests. An offshore operator may only need to change part of its digital infrastructure.

This does not mean that blocking is ineffective. Repeated disruption can increase costs, reduce visibility and make it more difficult for an operator to maintain a stable Australian customer base.

However, blocking individual domains is fundamentally a reactive measure.

The more sophisticated question is therefore whether regulators can disrupt the underlying business rather than repeatedly responding to its latest web address.

The growing importance of affiliate websites

Affiliate marketing represents another important layer of the offshore casino ecosystem.

An affiliate website does not necessarily operate the casino itself. Instead, it may publish casino reviews, comparisons, rankings, promotional material or other gambling-related content designed to send users towards gambling operators.

This creates a separation between the consumer-facing discovery process and the gambling operator.

For regulators, that separation can make enforcement more complicated.

A casino can disappear from a search result while an affiliate continues discussing it. Alternatively, an affiliate may promote multiple brands and replace one brand with another as enforcement changes the market.

Australian authorities have previously investigated affiliate services that advertised illegal casino services or facilitated access to them.

This makes affiliate marketing an important regulatory pressure point.

It also explains why search visibility matters so much to offshore operators. Maintaining a presence in search engines, comparison websites and other discovery channels can be almost as important as maintaining a particular casino domain.

The regulatory response has consequently expanded beyond the casino website itself.

Search engines and digital visibility

Search engines create another potential weakness in a website-blocking strategy.

Blocking a domain through Australian internet service providers can restrict direct access to that address, but it does not automatically remove every reference to the underlying gambling business from the internet.

Search results, social media posts, affiliate pages and other forms of digital content can continue to create awareness.

ACMA has responded by increasing engagement with digital platforms and search providers. Its compliance work has included efforts to have illegal gambling content removed from digital platforms and search results.

This represents an evolution from simple access blocking towards ecosystem disruption.

The distinction is important.

A website block attempts to stop a consumer reaching a particular destination.

Platform-level enforcement attempts to reduce the number of pathways through which consumers discover that destination.

The second approach is more complicated but potentially more durable.

Offshore operators and brand identity

Another adaptation is the use of multiple brands and corporate entities.

An offshore gambling business may operate through a corporate structure involving separate brands, companies, domains, payment relationships and service providers.

This can make it difficult for consumers to understand who ultimately operates a gambling website.

It can also make regulatory investigations more resource-intensive.

ACMA has noted that offshore illegal gambling services can operate with significant anonymity and that domain privacy arrangements can make identifying ownership difficult.

For consumers, this creates an additional problem.

A familiar-looking website does not necessarily reveal the identity, jurisdiction or regulatory status of the business behind it.

This is particularly important when a website presents itself as an Australian casino but is actually operated offshore.

The regulatory challenge is therefore partly an identity problem: identifying the business behind the website is often more important than identifying the website itself.

The role of offshore jurisdictions

Jurisdiction remains one of the biggest structural weaknesses in the Australian regulatory model.

Australian law applies strongly within Australia, but many illegal gambling operators are based overseas.

An Australian regulator can investigate activity affecting Australians, issue warnings and pursue disruption measures. However, directly regulating an overseas company is considerably more difficult when that company has no Australian licence, office or substantial local presence.

This is why ACMA has increasingly worked through third parties.

• Internet service providers can block websites.
• Domain providers can take action against domains.
• Hosting providers can disrupt infrastructure.
• Digital platforms can remove advertising or promotional content.
• Search engines can reduce the visibility of prohibited services.

These relationships effectively extend the reach of Australian enforcement without requiring every offshore operator to establish a physical presence in Australia.

However, they also create dependencies.

The regulator must identify the appropriate intermediary, demonstrate the relevant conduct and obtain cooperation.

That process can be effective, but it is inherently more complex than regulating an Australian-licensed gambling company.

Why VPNs create a regulatory challenge

Virtual private networks are frequently discussed in relation to blocked online services because they can alter the apparent location of an internet connection.

From a regulatory perspective, this illustrates a broader limitation of access-based enforcement.

If regulation depends partly on identifying whether a consumer is located in Australia, technologies that obscure or alter apparent location can complicate enforcement.

However, VPN access does not turn a prohibited Australian gambling service into a licensed one.

This distinction matters.

The regulatory issue is not simply whether a consumer can technically reach a website. The underlying question is whether the operator is lawfully providing a prohibited service to Australian customers.

For this reason, ACMA’s enforcement strategy has increasingly focused on the operators and infrastructure supporting illegal gambling rather than relying exclusively on consumer-side blocking.

Payment infrastructure is another pressure point

Payment processing is potentially one of the most important areas for regulatory disruption.

An online casino needs more than a website. It requires commercial infrastructure capable of accepting deposits, processing withdrawals, managing accounts and maintaining customer relationships.

This creates potential points of intervention.

ACMA has previously engaged with payment and software providers as part of disruption activity against illegal gambling services.

The advantage of this approach is straightforward: disrupting critical commercial infrastructure can be more effective than repeatedly blocking individual domains.

The challenge is that international payment systems are diverse.

Different operators can use different financial arrangements, intermediaries and providers. New relationships can also emerge when existing infrastructure becomes unavailable.

Consequently, payment disruption can increase operating costs without necessarily eliminating the offshore business.

Software suppliers are an overlooked part of the ecosystem

The gambling operator is only one component of an online casino.

Behind the consumer-facing website may be a network of software suppliers, game providers, platform providers, hosting companies, payment services, identity verification systems and marketing partners.

This creates a regulatory opportunity.

If an illegal casino depends on a relatively small number of critical infrastructure providers, enforcement can potentially target those relationships rather than each individual casino brand.

This is a more strategic model of enforcement.

Instead of asking, „How do we block the next casino website?”, regulators can ask, „Which infrastructure makes these services possible?”

The second question can produce more significant disruption.

It also shifts regulatory attention from symptoms to underlying commercial dependencies.

The weakness of reactive enforcement

The central weakness in the current model is its reactive nature.

• A regulator identifies an illegal service.
• The service is investigated.
• A warning or other enforcement action follows.
• A website is blocked.
• The operator changes domains or modifies its digital presence.
• The regulator identifies the new service.
• The process begins again.

This can still produce meaningful results. ACMA reports that more than 1,700 illegal gambling and affiliate websites had been blocked since the first blocking requests in November 2019, while more than 230 illegal services had withdrawn from the Australian market since enforcement of the newer illegal gambling rules began in 2017.

But the numbers also demonstrate how persistent the market is.

A high volume of blocked websites does not necessarily represent an equivalent number of independent gambling businesses.

Some domains may represent different digital identities associated with the same underlying commercial operation.

This is why measuring success purely through the number of blocked URLs can be misleading.

A better regulatory measurement would consider whether the underlying operator lost Australian traffic, payment capability, advertising reach and customer relationships.

Regulatory arbitrage remains a major issue

Offshore gambling illustrates a classic example of regulatory arbitrage.

A business can locate different components of its operation in jurisdictions with different regulatory standards.

• Its customers may be Australian.
• Its corporate entity may be registered elsewhere.
• Its hosting may be located in another country.
• Its software may come from another provider.
• Its payment infrastructure may involve additional jurisdictions.
• Its marketing may be conducted through independent affiliates.
• This fragmented structure creates enforcement complexity.

Australia can regulate conduct affecting Australian consumers, but the underlying commercial infrastructure may sit beyond Australia’s direct jurisdiction.

The result is a regulatory system that often depends on cooperation between multiple private and public entities.

The consumer protection gap

Perhaps the biggest weakness of offshore casinos is also the strongest argument for enforcement.

Australian consumers using illegal offshore gambling services may not receive the same protections associated with regulated Australian gambling services.

This can affect dispute resolution, account safeguards, responsible gambling mechanisms, identity controls, transparency and the ability to recover funds.

An offshore casino may appear attractive because of game selection, promotions or international branding, but appearance is not evidence of Australian regulatory protection.

The consumer may also have difficulty determining which legal entity is responsible for an account or where a dispute should be pursued.

This creates an information imbalance.

• The operator understands its corporate and regulatory structure.
• The consumer often sees only a brand and a website.

Improving consumer awareness is therefore an important complement to enforcement.

The next phase of ACMA regulation

Australian gambling regulation is moving beyond simple website blocking.

The direction of policy is towards a broader enforcement ecosystem involving advertising, affiliates, digital platforms, infrastructure providers and stronger measures against illegal gambling services.

This is particularly relevant following the passage of the Interactive Gambling Amendment (Gambling Reform) Bill 2026.

The reforms introduce additional restrictions around gambling advertising and inducements and strengthen enforcement capabilities against illegal gambling services. Many of the reforms are scheduled to commence from 1 January 2027.

For offshore operators, this creates a more difficult environment.

• Maintaining an Australian-facing marketing operation becomes riskier.
• Affiliate relationships become more important to monitor.
• Digital advertising becomes more constrained.
• Commercial infrastructure can become a potential enforcement target.
• The business model therefore faces pressure at several points simultaneously.

Where the biggest regulatory weaknesses remain

Despite increasing enforcement, several structural weaknesses are likely to remain.

1. Offshore jurisdiction

The largest problem is still the physical location of many operators.

Australian authorities can disrupt access, but direct control over an overseas business is limited.

2. Domain replacement

Website blocking is inherently vulnerable to domain replacement.

The more rapidly an operator can establish a new digital presence, the greater the administrative burden on regulators.

3. Fragmented corporate structures

Multiple companies, brands and service providers can make ownership difficult to establish.

4. Affiliate marketing

Consumer acquisition can occur through third-party websites rather than directly through the gambling operator.

5. Digital advertising

Illegal services can potentially move between different platforms and promotional channels as enforcement changes.

6. International payment infrastructure

Cross-border payments create a complicated enforcement environment.

7. Consumer awareness

Some consumers may not understand the difference between an offshore casino that accepts Australian customers and an Australian-licensed gambling service.

8. Measurement of enforcement success

Counting blocked domains does not necessarily measure the number of underlying operators removed from the Australian market.

A stronger measurement framework would track operators, brands, traffic, advertising reach, payment access and repeat appearances under new identities.

What offshore casinos are likely to do next

The offshore gambling market is unlikely to disappear simply because individual websites are blocked.

Instead, operators that remain committed to the Australian market are likely to place greater emphasis on resilience.

That means reducing dependence on a single website, marketing channel or commercial provider.

From a regulatory perspective, this is precisely why enforcement is moving towards infrastructure and intermediary relationships.

The future contest is therefore unlikely to be simply „casino website versus ACMA”.

It is more accurately described as an ecosystem-level contest between a regulator and a distributed international commercial network.

The regulator’s advantage is legal authority within Australia and the ability to coordinate with Australian internet service providers, digital platforms and other infrastructure providers.

The offshore operator’s advantage is geographic distance, corporate flexibility and the ability to distribute its infrastructure across jurisdictions.

The effectiveness of Australia’s regulatory model will depend on how successfully it can close the gaps between those two realities.

Final verdict

Australia’s approach to illegal offshore casinos has become substantially more sophisticated.

Website blocking remains an important tool, but it is no longer the whole strategy. ACMA is increasingly targeting affiliates, advertising, domains, hosting relationships, digital platforms and other infrastructure that supports illegal gambling.

The biggest weakness is that the underlying businesses can be international while the regulatory objective is domestic.

That creates a continuing enforcement gap.

For Australian consumers, the practical lesson is straightforward: an offshore casino being accessible online does not mean it is legal or regulated for Australian customers. A professional-looking website, Australian currency, Australian-themed marketing or a familiar brand name does not establish Australian licensing.

For regulators, the central lesson is different. The most effective long-term approach is unlikely to come from blocking an ever-growing list of individual URLs. Greater value comes from identifying the commercial relationships that allow illegal operators to acquire customers, process transactions, maintain infrastructure and remain visible.

The future of Australian online casino regulation will therefore depend less on whether regulators can block the next offshore casino website and more on whether they can make the Australian market commercially difficult to serve from offshore.

That is the real regulatory battleground.

And as enforcement becomes more sophisticated, the offshore gambling industry will have to become more sophisticated as well.

Frequently Asked Questions

Are offshore casinos legal in Australia?

Online casino-style services such as online slots, roulette and blackjack are generally prohibited from being provided to Australians under Australia’s Interactive Gambling Act. An offshore website accepting Australian customers does not mean it is authorised under Australian law.

What is ACMA’s role in regulating offshore casinos?

The Australian Communications and Media Authority (ACMA) enforces Australia’s online gambling rules. Its measures include investigating illegal gambling services, requesting website blocks and taking action against services that advertise or facilitate prohibited gambling.

Why does ACMA block offshore casino websites?

Website blocking is intended to make illegal gambling services harder for Australians to access. It is one part of a broader enforcement strategy designed to disrupt offshore operators and reduce their ability to target Australian consumers.

Can offshore casinos simply change their domain?

Changing domains can allow an operator to establish another online presence after a website is blocked. This is one reason ACMA has identified alternate domains and replacement websites as an ongoing enforcement challenge.

Do VPNs make offshore casinos legal in Australia?

No. A VPN can affect how an internet connection appears geographically, but it does not change Australia’s gambling laws or give an offshore casino an Australian licence.

Why are offshore casinos difficult for Australian regulators to control?

Many offshore operators are based outside Australia and can distribute their businesses across different jurisdictions. Hosting, software, payments, marketing and corporate entities may all involve different countries, making direct enforcement more complicated.

What role do casino affiliates play in the offshore market?

Affiliate websites can promote gambling brands, publish reviews and comparisons, and direct users towards gambling services. This creates an additional layer between the consumer and the underlying casino operator and can make enforcement more complex.

Does blocking a casino website shut down the operator?

Not necessarily. A website block can restrict access to a particular domain, but the underlying business may continue operating through other infrastructure, brands or domains. This is why regulators increasingly focus on the wider gambling ecosystem.

How does ACMA target offshore gambling beyond website blocking?

ACMA can investigate illegal services and work with relevant internet, digital and industry intermediaries. Enforcement can involve domains, advertising, affiliate services and other infrastructure connected with prohibited gambling.

What are the biggest weaknesses in Australia’s offshore casino regulation?

The main challenges include offshore jurisdiction, replacement domains, complex corporate structures, affiliate marketing, international payment infrastructure and the difficulty of measuring enforcement by individual website blocks alone.

Are offshore casinos regulated like Australian gambling companies?

No. An offshore casino may hold a gambling licence in another jurisdiction, but that does not make it licensed to provide prohibited online casino services to Australian consumers.

What protections can Australian players lose when using offshore casinos?

Consumers may have fewer practical avenues for dispute resolution and may not receive the same protections associated with Australia’s regulated gambling environment. The legal and corporate location of the operator can also make disputes more difficult to resolve.

Will ACMA continue blocking offshore casino websites?

Website blocking is likely to remain an important enforcement tool, but Australia’s approach is increasingly focused on the wider ecosystem surrounding illegal online gambling, including advertising, affiliates and supporting infrastructure.
