The Les Wilson Barramundi Discovery Centre explains the fish that made Karumba famous. It is part hatchery, part local-history stop, and part wetland centre, with tours that show how Southern Gulf barramundi are bred and released back into the river system.
This is the most useful first stop in town because it turns the surrounding mudflats and fishing boats into a story. You leave knowing why the Gulf matters, why the prawning and barramundi industries shaped Karumba, and why so many visitors come here with rods rather than beach towels.
