Jade Mills joins Bron and Dr Beach to talk about a survey looking at the health of Port Phillip Bay. Then the University of Melbourne's Rebecca Morris and Teresa Konlechner will be in to talk about the natural approach to coastal restoration - is there a better way than more concrete walls and breakwaters to combat sea level rise and erosion? Dave Donnelly from Killer Whales Australia brings some exciting news about sightings and documented research into the extremely elusive Shepherd's Beaked Whale of Australia and New Zealand. And we'll even sneak in a dive report from Terri. BIG SHOW!
