Can I Purchase a UK Map from Australia

I went to compare the price of purchasing a UK map for my START 52 vs getting a GPS with a hire car, but this map does not appear to be available for purchase in Australia. Is that correct, or can I purchase this via another means? Seems like a costly overkill to have to purchase a world map + I am not even sure how well it covers Scotland, which is all I am really after.

Thanks in advance for any feedback you are able to provide.
