Hanson goes after Turnbull's better half

Pauline Hanson has taken a swipe at Prime Minister Malcolm Turnbull's better half in a stoush over Australia's immigration rate.

Lucy Turnbull is the head of the Greater Sydney Commission and told The Daily Telegraph that Sydney was far from full, drawing the ire of Senator Hanson, who withdrew support for the government's tax plan over immigration concerns.

"She's got her standard of living and way of life but many Australians don't have that. I don't think she's in a position to say whether Sydney is full or not full," Senator Hanson told Sky News.

Former prime minister Tony Abbott also said he respectfully disagreed with Mrs Turnbull.

"I'd say we are full and frankly, we're fed up," he told 2GB radio.

He argued Sydney did not have the infrastructure to cope with its population density.
