got some questions:
1. Do you now have a visa to enter AU?
2. Where are you currently located?
3. Are you a family man?
4. If you are, do you value your family (wife and kids)?
The thing that you are dreading of is at this time just a proposal. It will still go into a bi-partisan debate and legislature prior to being approved. It will take some or more time before it will be implemented.
In my POV, the government is right on this proposal, as cities are becoming more and more crowded and congested. They were not able to anticipate these influx of people to concentrate on major cities. This population explosion in cities resulted in higher cost of living, things became expensive. Crimes also exploded due to so many reasons.
Until you have answered the above questions, especially 4, don't make a hasty decision that will make you more regretful.
