g'day mate, <-- you'll be hearing this frequently. The Perth Jeep scene is a pretty friendly bunch you will see a few trips on here, Im sure there will be a seat available for you.
There is also the Jeep owners club of WA I have only just become a member and dont know much about them I know others are more active members
www.jocwa.org.au .
You are more than welcome to a seat in my JK whenever available a few tips would certainly be welcome!
Have you sorted out / have any ideas about where you will be living?
Dave
