They look quite nice, really clean and crisp. Can you tells us a bit more about how you made them? Just a little bit like Software used? where you found the Data?
@DaveB - I agree the first map looks Australia look very green and lush, but I think the lakes are symbolised appropriately as "Non-permanent"
Ah, I see that now that you pointed it out. The misleading part to me is the solid fill that's very similar to the shallow coastal waters. The dotted outline is very subtle and gets lost unless you know to look for it (or my eyes are just getting old!).
(or maybe Australia really is that lush and green, but the wiley Australians want us to think it's mostly desert so they don't get huge numbers of people wanting to move there...
