The Crossfires I listed are just the ones on the Gold Coast, runs from Qld/NSW border north for 42 Kilometers (30 miles) of beaches. Probably the highest concentration of Crossfires in Australia. Has taken quite a few months to track them down.
Checked the AMI site. There are still a few Rambler Rebels and Javelins around. Some are undergoing revamps. There is a maroon Javelin with a 340 cu.in. Chrysler that looks pretty good.
My cousin bought a new Javelin (6 cyl) in late 1970 and I was tempted but I bought a Valiant VG Hardtop in early 1971 (Body was 1968 Dart from the US with an Australian VF or VG Valiant front panels forward from the "A" pillars and fitted with a 245 cu. in. Australian straight 6 cyl "Hemi").

Check out Mopar Motors in Melbourne if you get a chance. Big into the Chrysler scene. Has a Prowler. Doing a custom PT from, I think, a damaged or repairable write-off PT.
Good luck with getting to Chryslers by the Bay.
