Removing tidal gates brings salt water and fish back to Queensland wetlands
Tidal gate removal along Queensland’s Mackay coast is bringing estuaries back to life, with juvenile barramundi already returning to channels their ancestors used for thousands of years. After a 45-foot opening was cut through a long-standing embankment, saltwater rushed back onto Yuwi native title lands — a moment elders described as deeply spiritual. The returning tides have also killed off roughly 80% of an invasive grass near Cape Palmerston National Park, letting native mangroves recover. Dozens of gates have come down so far, with hundreds more in the Mackay area alone awaiting attention. It’s a hopeful reminder that some of the most powerful climate and biodiversity wins come from simply letting nature back in.
