The first One Nation MP to be elected to the House of Representatives has taken his seat in the lower house, but has left the door open to voting against his party.
David Farley was sworn into parliament on Tuesday after winning the Farrer by-election in May, up-ending more than 70 years of the coalition holding the southern NSW electorate.
Mr Farley was led into the chamber by One Nation recruit Barnaby Joyce, who he will join on the cross bench, before taking the oath.
One Nation leader Pauline Hanson and other senators from the party were also watching from the floor of the lower house, who Mr Farley embraced after his swearing in.
A date has not been set for Mr Farley's first speech to parliament.
