Change race-hate laws: One Nation senator

Pauline Hanson's senators have been given the green light to vote according to their own will in parliament.

One Nation's newest senator Malcolm Roberts, who officially received his ticket to Canberra on Thursday, said his allegiance was to the Queensland people, not Ms Hanson.

"Pauline Hanson told me and every other candidate, if you disagree with the party, you have a responsibility to cross the floor and that convinced me about this woman," he told reporters in Brisbane.

Mr Roberts outlined some of his priorities in his new job, including family law court and tax changes.

He wants amendments to section 18C of the Racial Discrimination Act to allow free speech.

"When we have free speech curbed we don't talk about the real issues - tax, Islam, terrorism, the economy," he said.

The Queensland senator-elect also wants an inquiry into the Bureau of Meteorology and the CSIRO, the latter of which he's accused of "corrupting the science".

Mr Roberts is a staunch sceptic of the impact of man-made climate change, calling for changes to climate policy which assumes humans contribute to global warming.

"There is not one piece of empirical evidence anywhere showing humans cause (climate change)," he said.

The mining engineering graduate also declared himself a scientist saying scientists relied on the scientific method.

However, Mr Roberts was more circumspect on his support for government policies such as restoring the construction industry watchdog.

While he was against union corruption, he'd wait until seeing the ABCC bill before finalising his position.

Mr Roberts also backs a plebiscite on legalising gay marriage.
