I am looking for a source on the internet that will give me ranges for postal codes in Australia for metro areas, eg, 3200-3500 is Melbourne where the range would include all suburbs generally agreed to be part of metro Melbourne. If they aren't really in a range, than a list of all the Melbourne metro postcodes would work. I feel like I have only found ranges by state but those include rural areas. Any help very appreciated. The cities are Sydney, Perth, Melbourne, and Brisbane.

You know when you're filling out a online address form, and they ask for your postcode then find your full address? Yeah, that doesn't work for me. How do I fix this? [more inside]

I'd like to store people's postcodes and work out distances between them. I think I need a postcode-to-coordinates database, and then a way of working out the distances... [more inside]
