I can recommend A Complete Guide to Reptiles of Australia by Stephen Wilson and Gerry Swan. If you're interested only in the snakes in your area I can also recommend the Field Guide to Reptiles of Queensland. The pictures and detail are fantastic and both of these books can be purchased through Mike Swan Herp Books. Mike is very helpful and the service is prompt. Not only did we get a call from him to sort out a technical issue with an order within minutes of placing it, but it was on a Sunday!
Pretty sure the snake is a brown, though the resolution isn't the greatest. Since we're giving reasons; the ridge over it's eyes isn't as heavily defined as the Taipans I've seen and the scales behind it's head don't appear to be keeled.
