Australia has announced plans to formally designate the Islamist organisation Hizb ut-Tahrir as a terrorist entity under federal law, a move that will criminalise membership, support and advocacy for the group across the country.

The decision, taken by the federal government following advice from national security agencies, places Hizb ut-Tahrir on Australia’s list of proscribed organisations under the Criminal Code.

Once the listing takes effect, individuals who are members of the group, provide material support or publicly promote its activities could face significant criminal penalties.

Government officials said the designation reflects longstanding concerns about the organisation’s ideological objectives and rhetoric, particularly in the context of heightened global tensions and domestic security risks.

Authorities have emphasised that while Hizb ut-Tahrir presents itself as a political movement advocating for the establishment of a global Islamic caliphate, its narratives and activities are assessed as contributing to radicalisation and undermining social cohesion.

The listing follows a review process that includes security assessments and legal scrutiny.

Under Australian law, such designations are subject to parliamentary oversight and periodic renewal.

The government has framed the step as part of a broader strategy to counter violent extremism and protect the community, noting that the country maintains one of the most comprehensive terrorist organisation lists among Western democracies.

Hizb ut-Tahrir has operated in various countries for decades and is banned in several jurisdictions, while remaining legal in others.

In Australia, it has previously been active in holding public events and distributing political materials.

The new designation marks a significant shift in Canberra’s approach toward the group.

Civil liberties advocates have called for careful application of the law to ensure that enforcement targets unlawful conduct rather than legitimate religious expression.

Officials have responded by underscoring that the legislation is focused on conduct linked to a listed organisation and does not criminalise faith or peaceful political opinion.

Security agencies are expected to work with community leaders to communicate the implications of the listing and to reinforce Australia’s broader counter-terrorism framework, which aims to address both immediate threats and the underlying drivers of extremist ideology.
