Stop paying for anything to do with the family home. So I'm assuming you're working? Go to a friend's house or a men's shelter if you need. Sadly, at this point, you have limited options. You could go to the local police station and ask them to contact her to make a time for them to escort you to your house to collect some belongings, but if she says no then you're stuffed...
If you're not working, then you could be entitled to some financial assistance, so go to the local Department of Human Services Office. If you have kids - call Relationships Australia for help in organising for you to get to see your kids. Might work, might not...
Mate, I went to St Vincent de Paul to buy some clothes, I bought socks and undies from Big W and I slept in the car/friends places. Worst days of my life. But things will improve, you just have to start making good decisions to make it work.
So one absolute golden rule - do not go near her. If she calls you up, do not answer. Refuse all communication.
Why? Well, there are lots of men in jail whose crime was to agree to talk to their wife while they had an AVO against them. So if she calls you up and asks you to come to the house to discuss things and you go, you have broken the law. If you go to the house and she calls the cops you will go to jail.
