Mrs Bishop’s office has been contacted for comment.

Earlier this year it was revealed she spent more than $5000 chartering a helicopter from Melbourne to Geelong in November to attend a Liberal Party fundraiser.

The expenditure report, released on Thursday, showed Mrs Bishop continued to charter aircraft after the notorious November helicopter trip.

On March 6 this year, $4100 was spent on a return trip to Port Macquarie, where she attended the Hastings Heroine Awards – an event recognising local women leaders.

No direct flights are available between Canberra and Port Macquarie, but the journey can take less than three hours flying via Sydney.

A six-day trip by Ms Bishop to Vietnam in March and April cost taxpayers $19,218.99, including nearly $13,000 on flights.
