A man charged with terrorism offences after raids in Melbourne and central Victoria has told a court he believes the charges are a conspiracy against the "patriot movement".

Phillip Galea, 31, from Braybrook in Melbourne's west, has been charged with preparing or planning a terrorist act and collecting or making documents likely to facilitate a terrorist attack.

He was arrested Saturday after Victoria's Joint Counter-Terrorism Team raided properties at Braybrook, Bacchus Marsh, north-west of Melbourne, and Tatura, in central Victoria.

During a brief hearing at the Melbourne Magistrates' Court, Galea sat in the dock and made no application for bail.

He said he would fight the charges and believed they were a conspiracy against the patriot movement.

He is due to reappear in court for a committal hearing on August 9.

A member of the True Blue Crew, an anti-immigration group, told the ABC Galea was a member.

Assistant Commissioner Ross Guenther said Galea had been affiliated "with a number of organisations", but would not confirm whether he was a member of any particular far-right group.

No imminent threat to community: Premier

Victorian Premier Daniel Andrews said there was no immediate or impending threat to the community.

"We take the threat of terrorism very seriously," he said.

"There is no imminent threat, no threat to safety ... coming from the charges that have been laid against this particular person."

The Joint Counter-Terrorism Team comprises officers from the Australian Federal Police and Victoria Police.
