LADY Elliot Island has become the first island on the Great Barrier Reef to stop selling water in plastic bottles to try and reduce its carbon footprint.
The island, at the southern edge of the Great Barrier Reef, is leased by an eco-resort supplied with water by a desalination plant.
Managing director Peter Gash told the ABC a recent upgrade meant there was no longer a need to sell bottled water.
"Twenty to 30 bottles a day were getting sold and people were bringing bottles with them, but we can now tell them they don't need to bring a bottle," he said.
It is among a number of steps the island is taking to reduce its carbon footprint.
