Answer:
Yes, there are a number of legal considerations when running an online competition. You should consider how you are collecting personal information and compliance with the Privacy Act 1988 (Cth), and implement a Privacy Policy. You should also consider the state in which you are running the online competition, whether your competition is a game of skill or chance, as well as the total prize pool. This will effect whether you are required to have a trade promotion lottery permit or not.
