Listen mate, we all have the same issues pending, whether it is buying property, moving to the city, wanting our kids to go to university without having to pay international fees, etc, etc, etc. I have those too, so instead I try look at the positive aspects of what could happen and take whatever action I need to in order to avoid pitfalls. It spoils my day when I have to look at negative comments that remind me of what could go wrong.
We all want the grant period to decrease. My (very good) agent has confirmed that if all documents are in place then PR should be granted within a period of 12 to 13 months. This is the consensus of 1700 agents around Australia. If the CO's have to request further or updated info then your time may exceed 16 months.. It is also possible that the grant period may decrease but the department may not necessarily commit to that on their website.
Believe me mate, people don't enjoy negative comments like the previous ones made today, they don't excite anyone. I don't say you make them all the time, but it does not help if your latest comment is negative. If we think positive and give help and advice on this forum then hopefully good Karma will come our way
