Hi Gregg,
You will not be able to bring it back to Australia unless it has paperwork which proves it is at least 15 years old. Otherwise you have to meet ADRs which a CJ cannot possibly meet. I researched it at great length before importing mine.
Ring me on Brisbane 07 3353 2843 to make a time to go for a ride. My CJ is QLD registered on full rego and is garaged at McDowall.
