I’m trying to work out what i need to do in terms of visas this summer. as far as i know, i can get into the USA on the visa waiver programme as i am only there for a short time and will have an ongoing ticket around the world. in austrailia, i know i need to get a visitor’s visa. there is something called the ETA at this link http://www.eta.immi…. . does anyone know about this? is this what i need to get?
