Polymarket Australia: ACMA-Blocked, Not Just Self-Restricted

Polymarket Australia is not the same story as Polymarket Canada or Polymarket UK, where the platform restricted itself ahead of any government order. On August 13, 2025, the Australian Communications and Media Authority directed Australian internet providers to block Polymarket outright, after finding the site had breached the Interactive Gambling Act 2001 by taking bets on the 2025 federal election through paid social-media influencers. That is a harder wall than a close-only setting, and it came from a regulator, not from Polymarket.

Legal status in Australia

Polymarket is illegal to operate in Australia under the Interactive Gambling Act 2001, and the Australian Communications and Media Authority has acted on that finding twice over — first with a formal warning issued July 2, 2025, then with a direction to Australian ISPs on August 13, 2025 to block the site at the network level. That followed a Crikey investigation published April 29, 2025 alleging Polymarket paid TikTok and Instagram influencers, some with audiences over 900,000, to promote betting on the Australian federal election under tags like #polymarketpartner, and reportedly approached satirical program The Chaser about a paid partnership. ACMA classified election-outcome betting of that kind as unlicensed interactive gambling under the Act. Polymarket also lists Australia as close-only in its own terms, meaning even a user who evades the ISP block cannot open a new position — only exit one already held. On top of the gambling-law finding, the Australian Securities and Investments Commission issued its strongest warning yet on August 4, 2026, naming Polymarket specifically and telling Australians that offshore prediction markets carry no local consumer protection, no compensation scheme, and real exposure to counterparties trading on non-public information. No Australian court order or DFO-style enforcement letter has yet followed the ACMA action, but the block itself is a regulator directive, not a company choice — unlike the UK and Canada, where Polymarket restricted itself ahead of any government order.

State gambling authority: Australian Communications and Media Authority (ACMA) — issued a formal warning July 2, 2025 and directed ISPs to block Polymarket on August 13, 2025 for breaching the Interactive Gambling Act 2001. Australian Securities and Investments Commission (ASIC) separately warned against offshore prediction markets, naming Polymarket, on August 4, 2026.

Search “is Polymarket legal in Australia” and the answer is more settled than the Canada or UK version of this page: it isn’t. On August 13, 2025, the Australian Communications and Media Authority directed Australian internet providers to block Polymarket outright, after finding the platform had breached the Interactive Gambling Act 2001. Unlike Polymarket’s close-only decisions in Canada and Britain, this one didn’t come from the company. It came from a regulator with the power to order ISPs to act.

How an Election-Betting Investigation Became an ISP Block

The chain started with reporting, not an ACMA raid. Crikey published an investigation on April 29, 2025 alleging Polymarket had paid Australian TikTok and Instagram influencers — some with followings over 900,000 — to promote betting on the 2025 federal election, with posts tagged #polymarketpartner. The outlet also reported Polymarket had approached the satirical program The Chaser about a paid partnership. ACMA opened an assessment shortly after, issued a formal warning to Polymarket on July 2, 2025, and when that didn’t resolve the issue, directed ISPs to block the site on August 13, 2025. The regulator’s finding: taking bets on election outcomes through an unlicensed platform is interactive gambling under the Act, full stop, and paying influencers to drive signups doesn’t change that.

Timeline: April 29, 2025 — Crikey investigation published. Some weeks later — ACMA opens an assessment. July 2, 2025 — formal warning issued. August 13, 2025 — ISPs directed to block Polymarket nationally.

Is Polymarket Legal in Australia? What “ACMA-Blocked” Actually Means

This is a materially harder restriction than what Canadian and British users hit. In both of those countries, Polymarket itself chose close-only status — a platform decision made ahead of or separate from any binding order. In Australia, ACMA is the one that acted, using its Interactive Gambling Act powers to direct network-level blocking through Australian ISPs. Polymarket’s own terms also list Australia as close-only, which layers a second restriction on top: even a user who somehow reaches the site past the ISP block still can’t open a new position, only exit one already held.

Is Polymarket Legit, Given a Government Regulator Blocked It?

Worth separating, the same way the Canada and UK pages do. ACMA’s finding is about licensing — operating interactive gambling in Australia without authorisation — not about whether Polymarket pays out on resolved markets elsewhere. The company has settled huge volume on elections, sports and culture markets globally without a payout scandal. A platform can be legitimately blocked for breaking one country’s gambling law and still be a functioning exchange everywhere it’s actually licensed to operate. Both are true here at once.

ASIC’s 2026 Warning Adds a Second Regulator to the Story

Almost a year after the ACMA block, the Australian Securities and Investments Commission issued its strongest prediction-market warning yet, on August 4, 2026, naming Polymarket directly. Commissioner Alan Kirkland framed it in consumer terms: Australians using offshore prediction markets get none of the protections that come with an ASIC-regulated financial product, no compensation scheme if something goes wrong, and a real risk of trading against a counterparty holding non-public information. That warning didn’t create a new legal status for Polymarket — ACMA had already blocked it a year earlier — but it means two separate Australian regulators have now gone on record against the platform for two different reasons: one for unlicensed gambling, one for unregulated financial risk.

Two regulators, two findings: ACMA — unlicensed interactive gambling under the 2001 Act, ISP block ordered August 13, 2025. ASIC — no consumer protection, no compensation scheme, informed-counterparty risk, warning issued August 4, 2026.

Is It Safe to Route Around the Block With a VPN?

No, and this page won’t walk anyone through it. Beyond breaking Polymarket’s own terms — Australia sits in close-only status regardless of the ISP block — it means using a platform ASIC specifically warned about in 2026, with no Australian financial-services recourse if a market resolves against a trader unfairly or an account gets frozen. Getting past a network block doesn’t restore any of the protection that the block, and the ASIC warning behind it, both point to being absent. This isn’t a sportsbook and it isn’t a way to make money — a position can go to zero regardless of which country it’s traded from. 18+, and Gambling Help Online (1800 858 858) if it stops feeling like a choice.

Polymarket Australia — Frequently Asked Questions

Is Polymarket legal in Australia?

No. The Australian Communications and Media Authority found Polymarket in breach of the Interactive Gambling Act 2001 and directed Australian internet providers to block the site on August 13, 2025, after a formal warning issued that July 2. That is a government-ordered network block, not a case of Polymarket simply declining to serve the market.

Why did ACMA block Polymarket specifically?

A Crikey investigation published April 29, 2025 reported that Polymarket paid Australian TikTok and Instagram influencers, some with followings over 900,000, to promote betting on the 2025 federal election under tags like #polymarketpartner, and allegedly pitched a paid partnership to the satirical program The Chaser. ACMA opened an assessment after that report and classified the election-betting product as unlicensed interactive gambling under the Act.

Is Polymarket legit, given the ACMA block?

The ACMA action is a finding about unlicensed gambling under Australian law, not a fraud finding — Polymarket has settled enormous global volume on real-world events without a payout scandal attached to its name. Legit as a company and legal to access from Australia are separate questions, and only the second one has a hard no attached to it here.

Is it safe to use a VPN to reach Polymarket from Australia?

No. Beyond breaking Polymarket's own terms — which list Australia as close-only regardless of the ACMA block — it would mean using a platform ASIC explicitly warned about on August 4, 2026: no Australian financial-services protection, no compensation scheme, and a documented risk of trading against counterparties sitting on non-public information. Routing around an ISP block doesn't remove any of that.

How is Polymarket Australia different from Polymarket Canada or the UK?

In Canada and the UK, Polymarket restricted access to itself, ahead of or independent from any court or regulator order. Australia is the harder case: ACMA, a government regulator, directed ISPs to block the site outright over a specific Interactive Gambling Act violation. Polymarket's own close-only listing for Australia sits on top of that ISP block, not in place of it.

Could Polymarket become legal in Australia later?

Nothing announced points that way. ASIC's August 2026 warning came after the ACMA block, not instead of it, and Parliament's Interactive Gambling Amendment (Gambling Reform) Bill 2026 — passed August 19, 2026, taking effect January 1, 2027 — strengthens ACMA's takedown powers against unlicensed operators rather than opening a licensing path.
