bonfire2010

We are aiming to go back to Aus in 2015 on a permanent basis. My Perm Residence visa expired in 2011, and this time around we want to take my dad (who will be 74 at the time) as he doesn't have any other family here apart from me, my (Australian) husband and our son. Has anyone applied for either of these visas and can give any advice? I am wondering how far in advance to start the application process. Thanks!
