Man refuses to answer to name in Qld court

An indigenous man who renounced his Australian citizenship to head a self-declared sovereign nation has been remanded in custody in Queensland after refusing to acknowledge his former name.

Murrumu Walubara Yidindji - formerly press gallery journalist Jeremy Geia - was charged at Gordonvale in May after police allegedly caught him using number plates and a licence issued by the unrecognised Yidindji government.

When asked whether he was the man known as Jeremy Geia at Cairns Local Court on Monday, he replied: "I am Murrumu in the appropriate persona."

The man, who faces a number of charges, including breaching bail, said he had been detained and held in captivity against his will.

"I think the matter is of jurisdiction," he said.

"The Yidindji were excluded from the Commonwealth constitution act of 1901."

A picture posted to Twitter in May indicated at least seven sets of plates had been made.

Magistrate Jane Bentley said she couldn't grant Mr Geia bail because "this person, he says, is not him".

She remanded him in custody to reappear on Tuesday morning.
