Labor frontbencher Tony Burke has defended spending almost $2.2 million of taxpayer funds on travel in seven years, including charter planes and flying on VIP jets.
News Corp reports on Monday that since mid-2008, the manager of opposition business and opposition finance spokesman had racked up almost $600,000 in overseas travel.
Mr Burke who was a minister in the Rudd and Gillard cabinets, is also a regular charter flight user, claiming more than $400,000 in domestic travel.
The investigation found that the Sydney MP, who led the attack on former speaker Bronwyn Bishop's hiring of a helicopter to attend a Liberal Party fundraiser, claimed more than $1.1 million on domestic fares, travelling allowance, car costs and family travel.
He eventually repaid money for airfare spent on his family.
