One Nation senator Brian Burston will attend the inauguration of US President-elect Donald Trump after his party was specially invited by the Trump Inaugural Committee.

Senator Burston told Fairfax Media two tickets were arranged through Darren Brady Nelson, a former Team Trump adviser who now works for fellow One Nation senator Malcolm Roberts.

One Nation leader Pauline Hanson revealed the gift on Twitter on Monday, but said she would not attend due to domestic commitments, including the upcoming Western Australia election.

"I thought about it for a minute, it would be a fantastic opportunity, but I've got too much happening in Australia," she told News Corp.
