Australia's best 4WD Site - tell me if I am wrong - Treks, forums, if you intend going off track - in fact anywhere, you should visit this site.
Bureau of Meteorology

If you are going there, you need to know about the weather.

Grey Nomad 101
If you are new to caravanning, or even if you have owned one for some time, this site has excellent DVDs available to help you avoid all the snags you may not have thought about before you do the "Big Lap". Highly recommended.
Lesley Bray Photography

Lesley accompanied me on my Queensland trip in 2010, and took well over 10,000 images, many of which are featured on her website. She also toured southern Western Australia with me in 2011-2012, adding to her catalogue of images.
I never fail to be inspired when I look at her photos.
