Wow, I've read your opening post and have come to the conclusion that you are actually me (or I am you)!!! Let's see...
Past camping has been mainly in the South West of WA - me too
Recently upgraded to a new Camper so as to be able to go further afield - me too
Going to Esperance - me too (I'm leaving tomorrow!)
Planning on going to Cape Leveque / Gibb River Road - me too (I'm going June/July '11)
Now, if you tell me you're (also) a short, chubby little bugger with a penchant for Beez Neez honey/wheat beer then I will know for certain there are two of me
Welcome aboard!
