3 Tokens

The Fremantle Crocodile Park is still there, in Fremantle, Western Australia, though they probably don't use these turnstile tokens anymore. Most places that still use turnstile tokens (like Canberra's Black Mountain Tower) have switched to less-collectable blank metal washers. While I'm not sure about this particular token, theme park / swimming pool / animal sanctuary turnstile tokens typically sell for $5 to $10.

The German parking token could well have been used here in Australia, imported with a German-made boom-gate controller machine. I've certainly seen them plenty of times in coin dealer "miscellaneous" scratchtrays. Typically sell for a few dollars.

The Malaysian one is presumably an arcade game token. Unless there's something particularly scarce or noteworthy about the place mentioned on it that I'm not aware of, it will be another "miscellaneous - $2 each" item from a typical dealer here.
