    This podcast has open my eyes even more.

    I’m a scuba instructor and have dived all around the world and love the ocean to bits. The best thing about the podcast is it’s main focus is solving the problems. It has inspired me to do more things in my area to help the problem.

Talking Points

Recent interactions between the hosts and their guests.

Harry Maher on how much does bioretention cost ?
Q: What is the methodology of the bioretention cost study?
The researcher collected real costing data by surveying industry colleagues and asset managers, focusing on actual maintenance, rectification, and installation costs, and then categorized basins by size to derive per-square-meter costs and maintenance frequencies.
Doing bioretention better with Dan Rhodes
Q: How would you improve buyer retention (bioretention) assets across Australia?
Emphasize upstream effective primary treatment, offline configurations, flow distribution, and maintenance as core levers to increase resilience and performance, along with field audits and tours to validate improvements.
Doing bioretention better with Dan Rhodes
Q: Dan, welcome back to the Ocean Protect Podcast.
Acknowledge the return and segue into discussing the move to Ocean Protect and the evolution of his work, including the focus on maintenance, field testing, and turnkey asset delivery.
Untrashing Australia's northern coastline with Grahame Lloyd
Q: How long were you there for?
We spent eight days at Marchambar, with three days of travel each way, working in extremely remote conditions without modern comforts or infrastructure.
Justine Barrett on cleaning out the undergound garbage bins
Q: What is the core issue with GPT maintenance and why does it matter?
The core issue is that GPTs exist in large numbers, but councils are under-resourced and lacking enforcement, so GPTs sit filled and unmaintained, allowing ongoing litter and pollutants to reach the ocean; fixing maintenance would dramatically cut pollution.
