It’s a story that has gripped Australia’s fishing communities for decades.
The issue of fishing illegally has become a major campaign issue with a powerful lobby on the national level, and a range of groups have been trying to influence it.
The first big fishing groups were formed in the 1930s and 1940s.
Now, a series of recent studies has shown that the vast majority of the fish stocks are not caught illegally, despite the best efforts of fishers.
The latest research also shows that people are fishing illegally because they are concerned about the environmental impact of their fishing practices.
In this story we look at the reasons people do it and what the government can do to help tackle the issue.
