Senator Pauline Hanson says she fills her own plane with petrol and drives herself to the airport, parking in the budget carpark and getting a bus to the terminal.

The Queensland senator says she also always travels economy and if she needs to go to remote places she uses her own plane at One Nation's expense.

"I've still got my plane, well the party's plane, but all the trips I've done in that since the election I've filled it up myself," Senator Hanson told Sky News overnight.

Senator Hanson says she also drives herself to the airport and parks in the "cheaper" parking.

"I get on the bus with all the other people from the carpark and they look at me and say, why aren't you in the COMCAR, Pauline."

Amid a government inquiry into the abuse of political entitlements, the senator said she tries to do everything as cheaply as she can.

Senator Hanson also used the interview to boast of her two tickets to Donald Trump's presidential inauguration, which she revealed had been given to her by a US congressman who she refused to name.

The Queensland senator, who says she won't be making the trip to Washington DC, was secretive when asked who had issued her the tickets.

"It's come from a congressman in the states. Any more than that, don't ask me," Senator Hanson said.

"Only 20,000 tickets have been issued to go to it and two tickets have been issued to me — and the prime minister never got any," she added while laughing.

But Senator Hanson said that she wouldn't attend the inauguration as she has commitments to the party in Western Australia, with her team to make a trip west on Thursday.

The senator's One Nation party was given the green light yesterday as a political party in Western Australia ahead of the March state election.

As her party prepares to contest the upcoming Queensland election, Senator Hanson last night said they planned to investigate legislation to ban people wearing burqas.

"You know what I'm going to do, going to investigate? Ban the burqa in government buildings, and banks and schools," she said.

"We're going to lead the way in Queensland.

"We're going to make it … no driver's licence wearing the burqa, or anything like that."
