Hello guys, I am staying in Melbourne and holding a permanent residency visa subclass 175, I have migrated to Australia on 21st Jan 2011 and completed 4 years of stay. I am planning to apply for an Australian Citizenship by this month's end. My question – my home country passport which I am currently holding is about to expire on 27/06/2015, that means within the next 17 days. Do I need to renew my passport even though I'm planning to apply for an Australian passport? Please suggest. Thanks a lot.
