To get any fauna from the TS islands is extremely difficult. They are under the Federal authorities, so you would need to apply for permit to collect in Canberra and you can count your chances of success. Also, despite the fact that the islands are Aust. territory, any animals vould have to be quarantined in gov. approved quarantine facility (at your cost) just like any exotic imports. I amnot sure if "conservation value" fee applies there but if it does, it'll be a hefty one. From memory, the conservation value payable for Aussie GTPs is around 3K. To get to these island is not cheap either.
Buy a captive bred Aussie olive - that's my advice. LOL
