Hey, I have a question about mine and my girlfriends second year working holiday visa. We left Australia in October with our 1st year ending in December and we were supposed to be heading back in January. One thing has led to another and we have planned to head back in September/October. We have not yet applied for our second year visa (we have the 88 days). My question is about the length of time we have been out of Australia, my thinking is that there must be some sort of limit on how long you can be out of he country before they would let you back in. Obviously come October it would be a year since we left but only 10 months since our first visa ended. Is there a limit on how long you can be out of the country? Is there a limit on how long you can take to apply for a second year visa? Any info you have would be fab, the immi website doesn't mention a timescale, only that you need your 88 days. Cheers!
