Queensland scientists brave crocodiles and deadly jellyfish to regrow seagrass

James Cook University team hope replanting project will be a blueprint for restoring underwater meadows on Great Barrier Reef

Researchers have been forced to avoid crocodiles, deadly jellyfish and even quicksand-like mud to replant seagrass beds south of Cairns as part of a project they hope to expand across tropical Australia.

The underwater meadows at Mourilyan Harbour were once thriving habitats, providing food for prawns, dugongs and green sea turtles.
