The 1990s was a wild west era for fishing on the Great Barrier Reef. Even after being declared a Marine Park and a World Heritage area, more than 95% of the Great Barrier Reef was still being fished, and things were heading downhill fast. Then came a bombshell report that exposed what was really going on beneath the surface -- and all hell broke loose. What followed was a fierce battle known as the ‘Trawl Wars,' and unfortunately, it did not happen in a galaxy far, far away.

In this episode, we’re joined by legendary conservationist Imogen Zethoven, who was made Officer of the Order of Australia for her groundbreaking campaign to create the largest network of no fishing zones, also known as Green Zones, in the GBR Marine Park. Imogen shares how the fight was won -- and why the battle to protect our oceans is far from over.
