Foreign Minister Julie Bishop claimed the largest amount over the period from January 1 to June 30, according to the latest figures on parliamentarians' entitlements published by the Finance Department, totalling $839,810.

At least two of Ms Bishop's colleagues have also come under pressure after charging taxpayers to attend a New Year's Eve party hosted by Prime Minister Malcolm Turnbull.

George Brandis, Peter Dutton and Mitch Fifield were on official business in Sydney on New Year's Eve in 2015 with a combined travel bill to taxpayers close to $7,000.

The offices of Senators Brandis and Fifield both described the event as an "official function at Kirribilli House".
