A severe weather warning covers Queensland's Herbert and Lower Burdekin Coast on Wednesday with the possibility of rainfall totals reaching 240mm.
The Bureau of Meteorology is warning flood-weary towns like Townsville, Palm Island, Ayr, Giru, Lucinda and Ingham are in the firing line.
Ingham was one of the hardest hit during the February flood disaster, with two lives lost in floodwaters that also damaged roads and shut down power for days after the nearby Herbert River broke a record level from 1967.
The region was battered by heavy rain in the last 24 hours with 287mm at Toolakea, 284mm at Bluewater and 242mm at Townsville.
Flood warnings are in place for the Herbert and Bohle Rivers, and meteorologist Miriam Bradbury warned any further rainfall may cause swollen catchments to rise.
Heavy rainfall is expected to ease briefly across the Herbert and Lower Burdekin on Wednesday afternoon before resuming on Thursday.
Ms Bradbury said the downpours should clear on Friday although showers will persist into the weekend.
The region is still reeling from record February falls which triggered widespread flooding that forced people to evacuate and isolated communities.
After just weeks of sunshine, north Queensland is again bunkering down with wet weather set to persist over the coming days.
Local mayor Ramon Jayo said many were on edge with the wet weather set to stall efforts to fix road damage from February's falls.
"There's still a lot of trauma," he told AAP.
The army at one stage were called in to help Ingham recover, rebuilding a bridge that was destroyed by floodwaters to ensure fresh supplies.
February 2025 was the wettest month in history for some north Queensland towns with Paluma near Townsville recording more than two metres of rain - double what Sydney receives in a year.
At one stage, 70 schools were inundated and more than 30,000 homes lost power.
In Queensland's southeast, recovery efforts after ex-Tropical Cyclone Alfred are under way with the prime minister visiting Hervey Bay.
The community was saturated by about 400mm of rain in hours barely a week ago with more than 1600 properties affected.
Anthony Albanese said more than $46 million of federal financial assistance had already been accessed in the wake of Alfred.
"At the worst of times we always see the best of the Australian character," he said on Tuesday.
"And here in Hervey Bay, like other communities, that's precisely what we've seen."
