mate you really wanna think this through. So for 2 yrs - assuming you get it varied - which is probable - but you're gonna have to spend a few grand on a solicitor... BUT once it is varied so you can return to family home, you will not be allowed to argue with the partner for 2 yrs. Don't matter how silly the partner is. If the partner chooses to call the cops and say you've been naughty, you will be arrested.
Look I hope you and partner sort it out... But from my experience, once things have gotten to a point where one person has spoken to the police - for what ever reason.... the relationship is obviously on shakey ground. But for your own sake get used to the idea that if there is any form of argument, you need to leave the house and not return until partner agrees that there is no more argument. If you do get it varied, pack some clothes etc in an evacuation bag and be prepared to leave on one minutes notice if there is an argument. From my experience my now ex, thought the AVO was great, she was happy to continue with the relationship knowing that I could no longer argue about anything because she could call the cops.... I get home from work - Wifey would say - I bought some nice new sunnies, they cost $500. Aren't they nice. Now the obvious answer is $500 sunnies are you crazy....
One more thought - go waste some money on a solicitor.... Maybe a solicitor can get the thing thrown out. But that is dependent on the details of what is in your partner's police statement...
