Me and my partner lodged out application for defacto 6 months ago and are still waiting. Our agent said that the time spent waiting counts towards evidence of being together so if you apply before the 12 months by the time they view your application you will have been together over the 12 months maybe even longer. Iv been told I may have to wait a further 6 months before we here anything so that time all adds up. Just keep every bit of post with your name, date and address. Get loads of joint things like joint car ownership, joint gym membership, joint bank account, joint phone bill even mobile (were joint with telstra) we also got our tax return as a joint tax return which states we are defacto which our agent was pleased with. Hope this helps
