Labor has signalled it will demand the resignation of Bronwyn Bishop if it emerges the Speaker signed a form indicating a chartered helicopter flight to a Liberal fundraiser was for official business.

The leader of opposition business, Tony Burke, called for the release of original documentation surrounding the taxpayer-funded travel and said there was “absolutely no way” Bishop could remain in the role if that were the case.

Bishop faced mounting political pressure this week about her use of entitlements, which included an expense of $5,227.27 for chartered flights from Melbourne to Geelong and back on 5 November 2014.

The Speaker announced on Thursday she would repay the charter flight money even though she maintained her belief that the travel “was conducted within the rules”.

Bishop must also pay a penalty of $1,307, because new rules implemented after a series of parliamentary expenses scandals in 2013 require politicians to repay an additional 25% of any adjustment to travel claims.

Labor continues to pursue the issue, pointing to a standard government form for charter certification for parliament’s presiding officers that says “office holders may use charter transport (including aircraft, helicopters and other vehicles) for their personal transport in connection with their office holder duties”.

According to that form, the office holder must certify that “knowingly giving false or misleading information is a serious offence under the Criminal Code Act 1995” and that they “travelled on the charter and it was provided for official purposes”.



Burke said on Friday that Bishop should release the document that she had signed. The contents of the form would determine whether Labor would demand her resignation from the key role of presiding over the lower house of parliament, he said.

“The normal form would say this was official business and would also say that there are serious criminal penalties if this is put in error,” Burke told Channel Seven’s Sunrise program.

“Now, if she signs it off in the normal form and it is, you know, a Liberal party fundraiser that she’s gone to, then that’s the end of the matter, she can’t stay as Speaker, absolutely no way.



“People make honest mistakes and we all know people can make honest mistakes but you don’t accidentally get on to a helicopter and turn up at a Liberal party fundraiser, so we need to find out and the government needs to release this document for us to work out exactly what it is that Bronwyn Bishop has claimed she has done.”

Guardian Australia is seeking comment from Bishop’s office about which form she signed, whether she will release it, and how the event in Geelong was consistent with her office-holder duties.

The Speaker denied wrongdoing when she announced the plan to repay the funds on Thursday afternoon. “Whilst my understanding is that this travel was conducted within the rules, to avoid any doubt I will reimburse the costs,” she said in a brief statement.

The opposition leader, Bill Shorten, had earlier demanded intervention from the prime minister, Tony Abbott, saying the case showed that Bishop “thinks she is so important that she can’t even be bothered getting a car between Melbourne and Geelong, a one-hour car trip”.



The treasurer, Joe Hockey, added to the pressure by agreeing with a radio interviewer that the helicopter trip did not pass “the sniff test”.

“Look, instinctively it doesn’t,” Hockey told 2UE. The treasurer responded to repeated questions about the Speaker’s expenses by calling on Bishop to explain matters.



After the repayment announcement, senior ministers sought to move on from the matter.

The foreign affairs minister, Julie Bishop, said she would not pass judgment because she did not know the context or the circumstances in which the trip was undertaken. “But what I do know is that she has decided to repay the amount, including a penalty, so I think that should be the end of the matter,” the minister told ABC’s 7.30 program.

The leader of the house, Christopher Pyne, said the Speaker was “doing a superb job” and had his full support.
