Flooding is expected to worsen in the far north-east of the state, in the wake of widespread rain, including along the east coast.
A heavy rain band has moved across much of Australia in the past week, with this contributing to high river flows in south-west Queensland, which are expected to reach SA in the coming weeks.
The State Emergency Service has issued a flood warning to those in the Inland Rivers community, and those planning to travel to the North-East.
Higher flows are expected to reach SA along the Diamantina River and Cooper Creek in the coming days.
The Diamantina River at Birdsville, Qld, is at 5.9 metres, according to the Bureau of Meteorology, and while it is falling, renewed river rises are said to be likely at the weekend or early next week as additional floodwater from upstream arrives.
Access to Birdsville township from SA is already closed, due to road closures, with floodwaters expected to cover more routes.
The peak flow entering SA on Cooper Creek is not expected for another week, at which time the causeway at Innamincka will become impassable and remain that way for three to four weeks.
The SES says the situation is similar to that of 2019, or potentially even higher.
Transportation and movement of local communities and travellers could be impacted in the coming weeks.
Travellers are being urged to visit traffic.sa.gov.au/) for the latest on outback road closures and impacts.
Those living in the North East are advised to prepare by moving stock, stocking up on non-perishable items of food and water and readying any pumping equipment.
Those planning to travel in the area should check weather and road conditions prior to travel, carry additional fuel supplies in case alternative routes are required, take extra food and water in case of delays and inform people of travel plans and advise them after arriving safely.
