Hizb ut-Tahrir Australia has penned an open letter to ASIO director-general Mike Burgess, criticising his assessment of the radical Islamic group, as it vows not to disband.
The organisation claimed Burgess acted as a "propaganda mouthpiece for those seeking to demonise Islam and Muslims" when he called out the group for threatening community cohesion while strategically remaining within the confines of the law in a speech in November.
"This lecture was never about presenting facts but about advancing agendas," Hizb ut-Tahrir Australia wrote.

Hizb ut-Tahrir Australia added that, "Staying within the law is not circumventing the law, it is the law."
Hizb ut-Tahrir is a radical political organisation that aims to establish a global Islamic caliphate, with headquarters in Lebanon and branches across the world.
The United Kingdom listed the group as a terrorist organisation last year after it praised the October 7 attack against Israel and referred to Hamas militants as "heroes".
Hizb ut-Tahrir has also been banned in Germany, Egypt, Bangladesh, Pakistan and other Central Asian and Arab countries.
In Australia, the federal government is seeking to list them as a hate organisation under a package of reforms responding to the December 14 terrorist attack at Bondi.
The bill would lower the threshold of what is considered a hate organisation, with Home Affairs Minister Tony Burke signalling Hizb ut-Tahrir and the neo-Nazi National Socialist Network will be captured under the proposed change.
"For a while, they have created a pathway for others to engage in violence, but have been careful to not explicitly call for it themselves," he said on Monday.
"They've kept themselves just below that threshold."

Parliament will debate the bill on Monday and Tuesday, with the Coalition poised to oppose the laws.
National Socialist Network's Thomas Sewell confirmed the group and other associated groups will disband the night before the government tables the bill.
He said there was no way to avoid being banned if what he described as "some of the most draconian laws the West has ever seen" passed.
In response to questions about whether it would also disband, Hizb ut-Tahrir Australia's lawyer Zaid Hamdan El Madi said the group cannot be banned.
"Hizb ut-Tahrir is based on an Islamic political worldview," Madi told 9news.com.au.
"Unless the government is proposing to ban Islamic ideas, it cannot ban the ideas of Hizb ut-Tahrir."
