CABINET ministers Scott Morrison and Julie Bishop both conceded on Wednesday that under-fire Speaker Bronwyn Bishop was considering her position.
Following revelations of Mrs Bishop's $5000 helicopter ride to a political fundraiser and $600 return flights from Sydney to Albury, where she attended the wedding of former MP Sophie Mirabella in 2006, News Corp reported on Wednesday she had charged taxpayers $288 in travel allowance to stay in Brisbane on the night of Liberal MP Teresa Gambaro's wedding in 2007.
Deputy Liberal leader Julie Bishop conceded on Channel 9 the Opposition would use the travel issue when Parliament returned.
"I'm sure Speaker Bishop will take that into account as she considers her position," she said.
Mr Morrison said he was not "one to offer public lectures to my colleagues on these things", but added, "The Speaker, I think, is consulting with her colleagues and I think that's the appropriate place for those discussions to take place."
