Residents living near the Murray River in South Australia are in a race against time as floodwater rapidly moves downstream and threatens to inundate homes and livelihoods.
Authorities are warning there will now be two flood peaks, with 175 gigalitres a day expected for the first in early December and 185GL a day a few weeks later.
Residents in multiple riverside towns are preparing by building levees and moving their valuables to higher ground.
