Do I need a return ticket? If you enter Australia on a one way ticket you may be asked by Australian Immigration authorities on arrival at the airport as to what your plans are for departing Australia. You would need to explain your intentions to the officer and the officer needs to be satisfied that you do not intend to stay beyond the period which your visa allows. While not a mandatory requirement, you may wish to carry a copy of your bank statement to demonstrate you have sufficient funds to purchase an airline ticket out of Australia.
