The City of Fremantle is refusing to be bullied by the Turnbull government claiming it will not move its Australia Day celebrations back to January 26 after it was threatened with having its citizenship ceremonies revoked.

Assistant Minister for Immigration Alex Hawke had written to the city claiming the council would be banned from holding citizen ceremonies because it breached the Australian Citizenship Act 2007 by "politicising" its banning of fireworks and its plans to hold a "culturally-inclusive alternative event" on January 28 instead.

"The government's firm position is that citizenship ceremonies are non-commercial, apolitical, partisan and secular and must not be used as forums for political, partisan or religious expression," Mr Hawke told the Fremantle Herald.

But Fremantle council put out a statement on Friday afternoon saying its One Day in Fremantle event on January 28 would go ahead because the council had not breached any code.
