Thanks all for the response.
Is there a link on the immi website where we can stay up to date on the total number of people in the queue? (65k as per the above which is crazy)
Also, I do have the option of lodging either a 143 or 864 (aged contributory). Seems like an unlikely shot but does the queue for 864 move any quicker than 143? I'm assuming the department would sync both visa categories by month.
I'm aware that 864 has its challenges where you need to ensure 'No further stay' is not mentioned on the current visa and the fact that you mostly need to stay here till grant.
