Whilst Australia has a process for listing threatened species, there is no longer a requirement for threatened species to have a recovery plan, nor is the government required to act on plans if they do exist. Even when a plan is written, we don’t monitor whether it is implemented. www.theguardian.com/environment/2019/mar/20/no-clue-envir…

Fly Point is Port Stephens is a great example with incredible fish diversity and abundance. See our 2018 paper rdcu.be/IuoS

I’ve noticed these long porcupinefish spend quite a lot of time chilling in grooves and overhangs, then fire into life from time to time. They are slow swimmers, so they seem to lumber along despite their frantically fluttering fins. Sydney Harbour North Head

North Head, Sydney Harbour. Noticeable on our surveys this year is the absence of tropical recruits and large fish. Apart from a few super-abundant small planktivores like mado and hulafish, there are very few fish left in these seas
