I mentioned in another post that I'd finally met up with Colin + Rose, a couple from the uk who had bought their land rover over to oz to do the big lap. We had a good chat as you do and talked 300tdi conversions amongst other things.
They are now back in the uk and are hoping to come back here in three years time, after putting a new chassis under their rover. Here's a link to their travels around Australia
I was pleasantly surprised to get a mention and a pic on their site. (half way down this page )
