A major upgrade of Australia’s flood warning network is underway, led by the Bureau of Meteorology.

Currently, there are more than 8,000 gauging sites across Australia and the Bureau owns about one-third of these gauges that it relies on to deliver flood forecasts and warnings. Over the next 10 years the Bureau will acquire, upgrade and maintain more than 1,500 more flood warning sites located in high priority catchments across the country.

The work will lead to a modernised and well-maintained network that will enhance flood forecasts and warnings and improve community preparedness for flooding.

The national Flood Warning Infrastructure Network Program, known as FWIN, began in Queensland, where around 1,000 gauges will be upgraded by June 2029. In 2024, the FWIN team have consulted with 64 Queensland councils about the flood warning sites to be included in the program.

The first site to be acquired and upgraded was the Cairns Kamerunga Bridge gauge in July 2024. The program will expand to all states and territories, starting next in New South Wales.

Funded by the Australian Government, ongoing maintenance will be shared between the Bureau and state governments and reduce the financial burden on local councils to maintain flood warning sites.
