in Newcastle is one of the biggest hobby shops in Australia with a huge range of trains, mountains and tracks
I don't understand the scales but check the link out and gives you a huge range of trains but average price bottom of the range is $200 and just goes up.

people might even find a good AC/DC train here as well
