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

Currently, there are more than 8,000 rain and river level gauge 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 around 1,600 additional 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. The 10-year program will reach all states and territories. Upgrades will take place in a staggered approach over several years.

FWIN's acquisition of rain and river level gauge sites across the country is scheduled to be completed by June 2033.

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.
