The answer depends on whether you're looking for the lowest minimum deposit or the highest maximum one. With Neosurf, the minimum deposit is AUD 10 and the maximum is AUD 10,000 — and that's the highest maximum that you can get. With Neteller, the minimum deposit is AUD 5 and the maximum is AUD 2,000. With JCB, the minimum deposit is AUD 5 and the maximum is AUD 2,500. AUD 5 is the lowest minimum that you can get.
