It is not problem that he knows about transaction, problem is can he realize that i use it on neteller as deposit.
Your father will only see that the bitcoins have already left your addres, and will only see another address (which can belong to anyboy, or e.g. it could be your another address, like a hardware wallet or paper wallet or anything). That address won't let him know that it's a neteller or not.
The real question is, what do you say if he asks you what you have done with the bitcoins he sent to you...
