Is there an australian law that would stop my ex seeing his son?

my ex is a jerk, he has psychologically problems, verbally and emotionally discourteous, contolling, he does drugs and is a very good manipulater.
We have be through mediation and came to an agreement for the next 6 months. he has supervised visit with his mum at her place. (our son is 13months old) i have a dvo out against him which has my son on the lay down. My ex hasnt been there for us at all. He go away for a few months and wasnt planing on coming back. He is honestly only seeing him for his mums sake. Just certain things he have said like when i found some lies he had said, he kept telling me not to punish his mum by not letting her see our son. and he said if anyone should suffer it should be me. I want to live my life span, i dont want to be pulled back by my ex because hes controlling and wont let me or my son do anything. After the 6 months can i change it to a contact nucleus? Or can i go to court now and try and get the contact heart in place now? Or anyway for him not to c hisso
Hi,
Look Im in much like situation as you, but In the opposite corner.
My hubby and I split after I discovered his affair. I slapped his face at our resturant and he took out a dvo against me.It was horrible. I have to go to court and admit to it as I couldn't afford to plead not guilty.Then he put our 3year old on the application as all right.
Do I deserve that . No. He did the wrong thing by having an affair and I did the wrong thing by slapping his facade. But do I deserve not to see my son ...No. and as much as I hate him , I wouldn't stop him from seeing our son either. Plus he now lives near the new girlfriends, so she looks after our son when hes at work. How do you think I cope with that??? It rips my soul to shreads.
There is other 2 sides to a story, but don't make the kids the essence or the expression of your hatred.

You are also trying to control him and manipulate him by using your son as a wepon or tool to gain him to say nice things instead of abusing you.
Unfortunatly, angry words are a sign of frustration and lack of commincation.
Why don't you love him more? Maybe your love can transform and reform your ex & you'll get married again. Then, all these problems will automatically grasp solved. Otherwise, I'm sorry to say, you shouldn't have married him in the first place. he`s get probs,mums good to have.but it`s only going to procure worse when mum dies,i`m a bloke with 5 great kids and we nearly fell into your trap,i`m better now and love everyone that was in that for us and spend everyday thinking about my darling and kids.do you love him,if so take him on your vocabulary to a psychiatrist and make him go and go again,and again and remind him if he loves you both be in motion again.I promise you it really does work.he just doesn`t have any confidecne right now ,that`s why he`s the track he is.but we know it`s no right.
