My 21 year old nephew got a working visa for Australia in Feb this year. He has a Canadian passport. He went down from Feb-June and is going back again on Sept. 18. This time, however, he has only bought a one way ticket. He has a place to stay and about $2000 plus a credit card. And, of course, a work permit valid until Feb, 2016.

Will he be denied entry without a return ticket to Canada? He is staying with me in HNL for 2 days prior to his flight HNL-SYD. Any chance he will be denied boarding at HNL without a return ticket and/or be refused entry when he arrives in AU and sent back to HNL? If so, I will make him buy a ticket as I don't want to be responsible for him (and don't want him staying with me any longer, lol). If he'll be ok without it, he'd rather wait to buy his return as he doesn't know where he'll be flying home from in AU yet. So, how tough is AU Immigration about having a return ticket on a work visa?
