As you are in Australia Johnno I think you will have difficulty getting this sort of stuff without buying from abroad with the attendant postage costs.

If you don't mind card construction, which can be very good these days, then MHS in the USA LINK have a good selection of American themed buildings which might be worth a look.

For a vintage track then GP Miniatures LINK have a good range.

Also check out Slot Track Scenics LINK for trackside accessories.

Pendle Slot Racing in the UK LINK can supply most of these things, they have superb customer service and ship worldwide at reasonable cost.
