Greens Senator Larissa Waters was sworn in as a senator for Queensland. Senator Waters left the Parliament in July last year as she was ineligible to sit in the Senate because of her dual citizenship. She was replaced by Andrew Bartlett who resigned from the Senate in the last sitting period. In his final speech to the Senate, Senator Bartlett signalled his intention to nominate for the electorate of Brisbane at the next federal election.
In cases where a Senate vacancy is caused by the resignation of a senator, section 15 of the Australian Constitution directs that the new senator is appointed by the parliament in the state from which the original senator was chosen.
