"Lonely Planet: Australia" is the definitive guide on Australia. The only problem with it is that it is written by Aussies (not necessarily a bad thing) and there is a lot of bias in it. I detected quite a lot of anti-British sentiments in it which is bad for a country that recently voted for the monarchy.
The book at times patronises the reader, other times exaggerates (it says that Canberra is definitely worth visiting: I've asked all my Oz friends whether they'd go there and they said no, especially the one who was born there).
So come on Lonely Planet, please don't rest on your laurels and boast about 25 years of travel guide writing. Be more objective and also give us better maps (maybe fold-out ones for principal cities) where you don't lose yourself because the road displayed is in the join of the book.
A string bookmark would also be good, like in the "Europe on a Shoestring". Why did you stop doing it?
All in all, I would still recommend this to any potential reader and buyer. Heaps better than the "Let's Go: Australia" that's for sure.
