Bron, Fam and Rex look at 1850s Hobson’s Bay, plastics in the oceans (yep it hasn’t gone away), and pay tribute to the late, great Bob Whiteway, OAM.

• Maritime Heritage guru Rex Hunter takes a look at defence installations in Hobson’s Bay during the 1850s.

• We speak with Ricki Hersburgh, Executive Director of Plastic Oceans Australasia about how education and science-based strategies are changing how we value and use plastic and ultimately stop it from getting into the world’s oceans.

• And we pay tribute to Victorian pioneer marine conservationist and educator Bob Whiteway OAM who passed away last week. We’ll speak with Bob’s dear friend, President of Marine Care, Rickett’s Point and Marine Education Science And Community, President Ray Lewis OAM, and Secretary Virginia Mosk, about Bob’s life, his legacy, and the critical role he played in ensuring Rickett’s Point, Beaumaris is protected as a Marine Sanctuary for generations to come.
