Fam Charko from the Port Phillip EcoCentre returns to talk about Plastic Litteracy - a concept of how much we really understand the recyclability of plastics. Fam will talk about the differences between degradable, biodegradable and compostible plastics. Then we're joined by Dr Angela Murphy from Federation University and Gary McPike from Barwon Coast Committee of Management to talk about a great study into beach use along the Barwon coast - who uses the beach and why, an upcoming review of the regulations for dogs on beaches in 2019, and how the results of the beach use research will feed into this process. And Dr Kate Charlton-Robb president of the Australian Marine Science Association and Marine Mammal Foundation director returns to give us a wrap of the Showcasing Victoria's Marine Environment event held earlier in the month, and about research she is doing into vessel compliance with dolphins and seal camera trap work. Also, Kade will be bringing in a mystery object he found while diving off Torquay during the week for Kate to identify live on air - no pressure Kate!
