We are a British family, based in Christchurch, NZ. We would like to travel to Australia for 7 to 9 days (starting around September 29th). We prefer to use public transport in Australia, e.g. trains and buses, rather than airplanes. We prefer self-catering accommodation, and we don't drink alcohol. I would like to ask for advises about places to go and things to do in Australia during this period.
