The above booklet says
"The costs will be considered reasonable and necessary provided they:
1. include travel from the sponsored persons’ usual place of residence in Australia to the place of departure from Australia
2. include travel from Australia to the country (for which the person holds a passport) specified in the request to pay travel costs, and
3. are for economy class air travel or, where unavailable, a reasonable equivalent.
Travel costs must be paid within 30 days of receiving the request."
This poses an interesting question. Let say an employee lives in Melbourne and works for an employer based in Melbourne. Before leaving Australia for good, as his employment is now terminated, he would like to tour Brisbane, as he has never been.
Could he have asked for cost of travel to Brisbane from Melbourne, plus cost of travel from Brisbane to London. Assume the two flights are 2 weeks apart, allowing that person to have 2 weeks to tour Brisbane.
