If one wishes to regulate the trade ever, one requires 3 components:
a) effective border controls and trained staff to identify taxa
b) effective penalties for illegal capture and maintenance
c) effective confiscation procedures and relocation programme for the confiscated stocks
d) regulation in-house and inland regarding private management and maintenance of wildlife and plants.
None of those issues are effectively met within Australia under Biosecurity guidelines (I left out the vet health issues as these are over-met out there). I find it particularly sad and disheartening that any confiscated stocks of endangered or any other taxa are nowadays routinely euthanised and not relocated into breeding programmes or zoos or quarantaine/holding facilities.
If I were the judge of this procedure I would term it a crime against mankind (as custodians of our Earth).
Now, all my fellow - well loved - Aussies posters may fall over my comments in the thread - pse be advised it is not personal - it is face-value, no-nonsense criticism of the present situation at your shores.
