On today's show we talk a combination of transport and waterways, catching up with a couple of our regular guests for the last time in 2018. Helen van den Berg from Friends of Steele Creek joins us to talk about the importance of incorporating Indigenous knowledge in water management practices and policies around Melbourne. Afterwards we speak to professor Patrick Moriarty from Monash Uni about energy use in transport, talking about Lithium batteries, electric cars and emissions. Join us next week for the last show before our summer break!
