Could some fellow Aussies help me out. this may have been posted before but I just need your guidance if someone can help.

So I’ve been on ed visa for a year and living in Thailand.

Heading back to Australia on the weekend to apply for the DTV soft power.

Could you tell me what proof I need to show the embassy as I, don’t have a car licence, the only bill in my name is a phone bill. I’m just staying with a friend while I apply. Could I provide a statutory declaration of where I am ??

Thanks everyone
