I purchased a copy recently and think it excellent.
If I could only purchase one field guide I would go for "A Complete Guide to REPTILES of Australia" By Steve Wilson and Gerry Swan but this is larger and more expensive.
The Field Guide for Queensland is organised very well and is excellent value. Here is the spiel from the Herp Shop web site:

NEW RELEASE
A FIELD GUIDE TO REPTILES
OF
QUEENSLAND
By Steve Wilson
Published by Reed New Holland, Australia. Jan 2005
Soft cover - plastic sleeve. 21cm x 15cm. 256 pages. Keys to Genera. Color photos. Distribution maps.
Queensland is home to an extraordinary diversity of reptiles. This is because it has so many different types of habitat. In the tropical rainforest lives one of Australia's most spectacular dragons, the Boyd's Rainforest Dragon. The arid south-west is home to the deadly Inland Taipan. In the deeply cracked black soiled plains of the Mitchell Grass Downs, Collett's Snake hides from the baking midday sun. In the far north there are isolated pockets of New Guinean animals, among them the magnificent Green Tree Python, which lives in the Iron and McIlraith Ranges and can be found by day coiled around thick vines. And few Queensland homes are without delightful nocturnal geckos.
A Field Guide to Reptiles of Queensland covers all of Queensland's 440 named species, including 135 that occur nowhere else. Colour photographs make for quick identification, aided by line drawings, keys, distribution maps and descriptions.
Steve Wilson has recently co-authored with Gerry Swan the authoritative A Complete Guide to Reptiles of Australia. His lifelong love affair with reptiles has taken him to some of Australia's most remote places. An excellent communicator, he has written and illustrated many articles and in 2000 he won Australian Geographic's Photography of the Year. For 18 years he has worked at the Queensland Museum, educating the public, identifying their specimens and raising awareness about Australia's unique biological heritage and how to conserve it.
The Herp Shop price - $34.95.
