Australian water quality trends over two decades show deterioration in the Great Barrier Reef region and recovery in the Murray-Darling Basin

This is the authors' abstract. We don't add key points for this paper.

The quality of Australian rivers within the North East Coast drainage division, which largely flow into the Great Barrier Reef lagoon, has declined over the past two decades, whereas river water in the Murray-Darling basin has improved, according to a water quality trend analysis for all of Australia.
