Speaker Bronwyn Bishop reportedly took a chartered flight to a Liberal Party fundraiser in the regional NSW town of Young five days after her controversial helicopter flight to Geelong.

Ms Bishop took the charter service to an event at the Young Services Club where she was a key speaker, the Herald Sun reports.

The flight was reportedly not listed in the six-month audit of travel expenses by federal politicians, however a spokesman told the newspaper the Department of Finance would include it in the next report.

Ms Bishop has come under fire after it was revealed last week that she took a $5000 taxpayer-funded return helicopter flight from Melbourne to Geelong for a Liberal fundraiser in November.

Allegations have also surfaced about a $88,000 taxpayer-funded trip to Europe.

The trip involved a stint in Switzerland where she unsuccessfully ran for president of an international parliamentary union.

She spent $14,000 on private limousines during the 15-day trip.

Ms Bishop has conceded the Geelong helicopter flight was an “error of judgement” and has agreed to repay the cost of the trip as well as a fine.

Opposition leader Bill Shorten has called for Ms Bishop to step aside, saying her position as Speaker is no longer tenable.

“This is now a test for Tony Abbott’s leadership,” he said.

Treasurer Joe Hockey told the Herald Sun the issue had “sucked up too much oxygen”.

“I haven’t heard of anyone who has taken a helicopter to a fundraising event,” he said.
