Travelling ministers can also now take more staff at taxpayer expense and have greater discretion on whether to undertake trips, provided they take into account cabinet meetings and parliamentary sittings.
The new conditions for travel follow the dumping of restrictions imposed by Tony Abbott that banned all first-class travel and in most cases limited the entourage to one or two staff members.
When elected prime minister, Mr Abbott issued a series of warnings to ministers and MPs about travel and electoral entitlements, rigorously policed by his chief-of-staff Peta Credlin.
