One Nation switch sparks Labor leader barb

NSW Labor leader Chris Minns says one of his former colleagues is "in the right party" after she announced intentions to run for One Nation at the March election.

Member for Bankstown Tania Mihailuk left the NSW Labor party in October last year after being sacked from shadow cabinet for accusing another party member of corruption.

On Tuesday, she revealed she would run for the NSW Upper House as a candidate with One Nation, led by fellow-former Labor politician Mark Latham.

Ms Mihailuk used the announcement to deliver a barrage of criticism of NSW Labor, saying if the party won the election the state would go "woke and broke".

"The Labor party has sadly lost its way to the left-wing extremists and property developer mafia that have taken over Labor like a cancer," she said.

Ms Mihailuk expressed her concerns over alleged issues including left-wing indoctrination in schools, religious freedom, gender fluidity and drug legalisation.

But Mr Minns brushed off the criticism.

"The only thing I think we all agree on is that Tania Mihailuk is in the right party," he told media on Wednesday.

Shadow roads minister John Graham pointed out Ms Mihailuk and Mr Latham had spent years trading barbs with each other and called their political partnership a "marriage of convenience".

Mr Latham once said Ms Mihailuk "doesn't have two brain cells to rub together", according to Mr Graham.

"Firstly, this is not how we should be talking about each other, we need to lift standards here in public debate," he said.

"Secondly, the state desperately needs fresh thinking and that is not going to come from Pauline Hanson's One Nation."

Ms Mihailuk was dumped from shadow cabinet by Mr Minns, after ignoring an ultimatum to stop launching political attacks on Canterbury Bankstown Mayor and upper house candidate Khal Asfour.

She used parliamentary privilege in September to accuse Mr Asfour of acting in the interests of disgraced former Labor powerbroker Edddie Obeid.

An independent review into allegations of misconduct and corruption later cleared Mr Asfour of any wrongdoing.

One Nation was contacted for comment.
