Melbourne MP Adam Bandt has defended his use of taxpayer funds during a trip to Sydney in the lead-up to the NSW election.

Disclosed parliamentary entitlements showed Mr Bandt charged $3000 to the public purse, for a two-day trip on February 28, that also included campaigning for the Greens in the state election.

He also campaigned with state candidates for Newtown, Jenny Leong, and Greens MP for Balmain, Jamie Parker on the Sydney visit, according to News Corp.

It was comprised of about $1720 in flights for his partner, Claudia Perkins, under family reunion entitlements and $395 for the MP’s travel.

Other charges included $775 for Mr Bandt’s flights and $128 in car travel.

The entitlements system allows parliamentarians to charge travel expenses for parliamentary, electorate or official business.

It does not include party-related travel, such as campaigning.

Mr Bandt’s spokesperson told News Corp he had not breached entitlements.

“Like all MPs, his partner is able to accompany him on interstate travel in certain circumstances and this was one of those,” he said.
