“I have today written to the Governor-General and tendered my resignation as Speaker of the House of Representatives effective immediately,” Bronwyn Bishop said in a statement.
Bishop has come under public scrutiny for a 2014 helicopter ride to the ruling Liberal Party fundraiser that cost Australian taxpayers an estimated $3,900.
Prime Minister Tony Abbott, who had placed the embattled speaker on probation two weeks ago, announced a comprehensive review of entitlements system abuse at a press conference on Sunday.
On Thursday, the Guardian revealed 15 additional instances where Bishop claimed travel allowances as families and human services committee chair in 2005-2006. The committee was not conducting hearings at the time, according to records obtained by the publication.
Bishop has repaid the money for her controversial 46-mile charter flight from Melbourne to Geelong, plus an additional 1,300 Australian dollars, and formally apologized last week.
