Inheritence and Power of Attorney questions please help? - australian power of attorney

Well, long story. My father was $ 40,000 for me and my aunt's attorney. He invested the money in a government of Australia. Company for a specified period. I can not touch the money until I'm 25 years old, is now 20 years, it's a way I can to revoke your power now that I make the decision on my own?
If the money earns interest aroused?

They said that the company charges for holding money. Is it likely that the interest be denied only $ 40,000 (cover) would be the fees? "My money is growing?

Thank you in advance.
