Julie Bishop reportedly had an empty RAAF jet fly from Canberra to Perth to pick up her and her partner after a charity dinner.

The foreign minister and her partner David Panton were the only passengers on the $30,000 taxpayer-funded flight to Canberra on October 18, The Daily Telegraph reports .

Ms Bishop represented Prime Minister Malcolm Turnbull at the event for WA Telethon donors but had reportedly completed her official duties the previous day.

The deputy Liberal Party leader said she used the RAAF jet because her function finished late and there were no commercial flights that could get her to Canberra by 7am for ministerial meetings.

MPs from the Labor Party as well as Ms Bishop's own party reportedly said that the minister should have cancelled her dinner engagement instead of using the RAAF aircraft at an estimated cost to taxpayers of at least $30,000.

Earlier this year another Bishop became embroiled in an abuse of entitlements scandal.

Veteran MP Bronwyn Bishop resigned from her role as Speaker of the House of Representatives amid a protracted abuse of entitlements scandal that came to be known as "Choppergate".
