Trump a 'revolting slug': NSW upper house

Donald Trump is a "revolting slug" unfit for public office, according to NSW Parliament's upper house.

Greens MP Jeremy Buckingham on Thursday tabled a motion condemning "mysoginistic, hateful" comments the US Republican presidential candidate has made against women and minorities, including his remarks revealed at the weekend describing sexual assault.

The motion also called out the divisive, destructive impact of hate speech from political candidates and agreed with those describing Trump as a slug unfit for office.

Mr Buckingham's motion was unanimously carried.

"It's clear that all reasonable and decent people find Donald Trump's behaviour obnoxious and that the world is hoping American voters reject his politics of hate," Mr Buckingham said.

Federal Trade Minister Steve Ciobo said the motion was unhelpful to enhancing Australia's relations with the US.

"I don't think it advances any cause whatsoever," he told ABC radio.

"And frankly it's a little gratuitous."
