This episodes brings together a number of perspectives to outline how particular natural spaces - in our case the underwater world - entered the public imagination of Victorians and sparked a political discussion that led to their wider protection.

We will chat with Mark Rodrigue from Parks Victoria, who looks after our Marine Parks and Sanctuaries in Victoria before we're actually embark on a short boat ride across Port Philip Bay and to go swimming with dolphins. Judith Muir, from Polperro Dolphin Swims, will join us and share with us her experience with the Bay as educator and eco-tourism operator

Interviewees:

- Mark Rodrigue, Parks Victoria, State-wide Leader - Marine and Coasts

- Judith Muir, Eco-tourism operator, Polperro Dolphin Swims
