The town that is further from the sea than any other in Australia is surrounded by water after record rainfall cut roads and isolated communities.

The 98-strong community of Eromanga in Queensland’s south-west has been inundated after heavy rain lashed inland and coastal regions, triggering widespread flooding warnings.

Opal mining town Eromanga, which is near the Queensland-South Australia border, is usually bone dry – in keeping with its unique claim to fame.

However, it has been hit by flooding this week, along with other outback towns Adavale and Quilpie, following record falls.

The Channel Country region reportedly had its wettest March day in 15 years on Tuesday after 130 millimetres of rain, with no relief in sight for a flood-hit Queensland.

There was up to 100 millimetres in other areas across the Channel Country, Maranoa and Warrego, as well as central and north-west regions.

Queensland’s central west has been one of the hardest hit from this week’s downpours. There has been 208 millimetres of rain at Bogewong and 169 millimetres at Stonehenge.

“These numbers are exceptionally high for this area, which is normally very dry,” the Bureau of Meteorology’s Angus Hines said.

Elsewhere in the region, forecaster Weatherzone says Winton – is having its wettest March in more than 142 years of records.

“In the 24 hours to 9am Wednesday, Winton saw 158.2 millimetres of rain, bringing its monthly rainfall tally to 279 millimetres,” it wrote.

“That exceeded the old March record of 249.8 millimetres (from 2018), with records being kept in the town since 1884.

“The overnight rain also brought Winton’s running annual rainfall total to 486.2 millimetres, which means the annual average rainfall of 385.8 millimetres has been comfortably exceeded less than a quarter of the way through the year.”

And there’s more still to come for central and south-west Queensland. A severe weather warning covered the area from Julia Creek to Charleville – an area spanning almost 1000 kilometres – on Wednesday.

The warning zone includes Longreach, Winton, Barcaldine and Quilpie, with up to 120 millimetres of rain possible on Wednesday.

There have also been more heavy falls in Queensland’s coastal regions, including one that is still recovering from devastating flooding.

North Queensland copped some of the worst of the wet weather, with 145 millimetres at Rollingstone, 142 millimetres at The Pinnacles and 115 millimetres in Townsville.

The region was also hit hard in February, when floods triggered by record rainfall claimed two lives, forced hundreds to evacuate and cut power for days.

“Rain will continue for most of the state today,” Hines said.

“Some of these areas have been wet since at least the weekend, meaning the rain that’s falling at the moment is falling on a saturated landscape.”

Major flood warnings have been triggered across central and western Queensland.

“Most significant rivers through the centre and west of the state are experiencing or expecting some flooding today or in the coming week,” Hines said.

In coming days, the rain will move south, with a “very wet day” forecast in coastal areas from central Queensland’s Yeppoon to southern NSW’s Bega, including Brisbane and Sydney, on Saturday.

In early March, south-east Queensland and northern NSW bore the brunt of ex-Tropical Cyclone Alfred that left more than 200,000 people without power.

The cyclone was the first in more than 50 years to impact Queensland’s south-east.
