What is the best proof of location document to use for the Sydney embassy for a DTV application?

When applying for a DTV from Australia while being a non-resident, using your valid Australian driver's license as proof of location is generally accepted since it contains your official address. Other options include providing a statutory declaration witnessed by a JP, or documents such as vehicle registration, phone bills, or tax statements that show your address. Some expats have also successfully used travel documents like boarding passes and hotel reservations.
