Australia's ACCC sues Amazon over Prime Video ad terms

Australia's consumer watchdog has filed Federal Court proceedings against Amazon, alleging the company used unfair contract terms in Australian Prime subscriptions to add advertising to Prime Video and then charge customers more to keep the service ad-free.

The Australian Competition and Consumer Commission said the case covers more than 1 million annual subscribers under Amazon Prime contracts between November 2023 and August 2025. It alleges Amazon introduced ads to Prime Video in July 2024 and left customers who wanted to avoid them with the option of paying extra.

ACCC chair Gina Cass-Gottlieb said consumers who wanted to avoid ads were left with no choice but to pay more to keep the service they had signed up for. The watchdog is seeking penalties, costs and consumer redress.

Amazon Australia said it had cooperated with the ACCC investigation and was reviewing the legal filing.

The ACCC's case

The regulator says five unfair contract terms allowed Amazon to make unilateral negative changes to the service without offering consumers a remedy. In the ACCC's account, those terms gave the company the ability to alter the subscription after customers had already signed up on the understanding that Prime Video was included in Prime.

The case is being brought under Australian consumer law provisions on unfair contract terms. If the court accepts the ACCC's arguments, Amazon could face financial penalties and other relief.

The commission also alleges Amazon's U.S. operations were involved in drafting the Australian contracts and implementing the ad rollout.

How Prime Video changed

Prime Video in Australia had been marketed as included in Amazon Prime before the ad rollout, according to the research packet. The ACCC says Amazon moved to an ad-supported model in July 2024 and then charged more for an ad-free experience.

That sequence is central to the dispute. The case is not only about the introduction of advertising, but about whether Amazon used contract terms to change a core benefit of the subscription after customers had already agreed to buy it.

The regulator's filing also points to the size of the affected customer base. The contracts under review covered more than 1 million annual subscribers during the period identified by the ACCC.

Amazon's response

Amazon Australia has not yet set out a detailed public defence in the material reviewed for this report. It said only that it had cooperated with the ACCC investigation and was reviewing the filing.

The first public reporting on the lawsuit came within hours of the filing, with multiple outlets confirming that the ACCC had taken the matter to Federal Court on June 30, 2026. The earliest sourced report in the research packet was published at 6:10 a.m. UTC, with additional coverage following shortly after.

Why it matters

The stakes extend beyond Amazon's streaming service. The ACCC is seeking penalties, costs and redress, and the case could become a test of how far subscription platforms can alter core benefits through contract terms after users have already signed up.

If the regulator succeeds, the proceeding could also sharpen scrutiny of other ad-supported subscription changes across digital services. The question at the center of the case is whether a company can change the value proposition of an existing subscription and then charge consumers more to preserve what they originally purchased.

Australian law allows substantial civil penalties for serious consumer-law breaches, giving the case commercial weight even before any findings are made.

What happens next

The immediate next steps are Amazon's formal legal response and the first court appearance. Reporting in the packet also referred to a Tuesday hearing, although the exact timetable beyond that was not yet clear.

Other open questions include whether the ACCC will publish the full statement of claim, whether it will seek interim orders and whether the case could lead to refunds, compensation or subscription changes for Australian Prime users.

For now, the filing is a closely watched test of consumer-law enforcement in Australia's streaming market and of how subscription services can restructure what customers get for the price they originally agreed to pay.
