Here's a reply I got from DPI after suggesting that perhaps the uncooked prawns shouldn't be bought into the country in the first place:
"Both the issue of importing green (uncooked) prawns and the country of origin labelling are managed by the Federal Government and as such the Department of Primary Industries and Fisheries does not control this legislation. However, DPI&F are taking proactive steps to ensure people are aware of the risks associated with using imported green (uncooked) prawns as bait and encouraging people to make the right decision."
So the Federal Government opens the gates and the DPI&F have to chase the horse that's bolted. Hmmm..... there are some clever people running our country
