I'm getting frustrated trying to get an iPad Sweepstakes offer approved on various mobile ad networks. (Where I can buy AU traffic)
This is what they're telling me: Users must not be required to provide financial information, make a purchase, or commit to a financial agreement in order to enter or qualify for a contest
What are my options ppl?
Honestly, the short answer is you need to test about 20 more traffic sources. That's a very respectful ad disapproval.
We all spend our money testing lots of traffic sources. Most likeky no one will tell you exactly where their bacon comes from. You can make a ton of money testing offers on jumptap, inmobi and other large sources but these guys are also becoming more strict with what they allow and competition is becoming more fierce, hard to get big volume now.
BUT all you need to do is put in some hard work researching, signing up and testing more sources and you may find out more than your bargained for 
Try adfonic, it'll give you a head start!
I've had recent goodluck with them, they're just lacking big big volume.
If they take long approving an ad, just email them.
