I've just applied through the ETA website for an Australian tourist visa. Departure date is end June, and my trip's only for a week.

After I've filled in all the details, the results are that it's not approved. Oh gosh why not? I fulfil every single requirement for the Visa. No criminal records, passport on the approved list, not currently in Australia..

My only suspicion is that I used a Visa debit card to pay for the online fee of AUD$20. Could that be the reason? Can someone confirm?
