thanks for the help guys!
i found it looks very smiliar to these Bedford OB buses
http://www.oldclassiccar.co.uk/40_bedfordob.htm , but it's the two curved glass windows (next the a pillar) at the front that are different. i've found that some older american Chevorlet buses have the same (or very smilliar) rear end, but still no luck in identify it correctly. i'm very keen to find out excatly what it is! And yes the bus is currently in a wreckers yard in australia, about a 2hrs drive from where it use to transport people to and from. and yes we do get snow in australia it may seem odd but for such a hot country but most of our snowfields are artifical, haha, still fun.
cheers again for your help fella's
