Labor is demanding Prime Minster Tony Abbott detail what work meetings he scheduled in Melbourne on Sunday after revelations he used a taxpayer-funded jet to attend a Liberal Party donor's birthday party.

Mr Abbott began his Sunday in Brisbane then flew to Sydney to attend New South Wales Premier Mike Baird's election launch, which began at 11am and concluded just after midday.
