The Victorian government’s decisions do a great disservice to expert’s time and carefully considered advice, and most importantly, the health of the places and wildlife we love.
After a 4y delay, @vicgovernment.bsky.social has released a disappointing response to the recommendations of an Expert Advisory Panel which reviewed the 1975 Wildlife Act, rejecting many critical recommendations from the Panel.
