"Battle weary" central Queensland landholders are in for yet another soaking heading into the weekend, the Bureau of Meteorology says.
The BOM's Brooke Pagel says showers will increase into widespread "moderate rainfall" in central and South East Queensland on Friday and Saturday.
A flood watch has been issued for catchments between Rockhampton and Caboolture for minor flooding from Friday.
"Overnight, we could potentially see up to 25 to 50 millimetres for some areas, particularly between Mackay and Bundaberg," she said.
Up to 10mm are expected in Emerald, Moranbah and Gayndah on Friday.
Ms Pagel said the rain could reach Tambo and Hughenden on Saturday, but the focus was on the east.
"Saturday seems to be that main day where we do have a really strong indication of those heavy falls, potentially up to 100mm in some areas, potentially between Rockhampton and Bundaberg and to K'Gari Fraser Island as well," Ms Pagel said.
"We are looking at most of the coastal region across Queensland from the North Tropical Coast down, and we also have strong wind warnings associated with that as well.
"The main catchment we are keeping an eye on is the Mary River and the upper creeks of the lower Brisbane River as well, as they still are slowly easing and draining off."
'Super saturated'
Mary River Catchment Coordinating Committee operations manager Brad Wedlock said landholders in the Wide Bay and Sunshine Coast regions were "battle weary" after several floods this year.
"We all just wish it'd stop raining for a bit and let it dry out," he said.
Mr Wedlock said many were dreading more rain after having little time to recover from the destruction of this year's repeated flood events.
"We just keep breaking records all through the catchment with each of these events," he said.
"If we have a fourth flood in the space of four months of some significance, let's hope it's not as bad as it was last week or in February."
Mr Wedlock said exhausted landholders were as prepared as they could be, but landslips, road flooding and infrastructure damage were hard to predict.
"[The Mary River] just keeps getting a battering and those river banks are already super saturated," he said.
Dams, waterways full
Gloria Andrews said 10 inches of "very welcome" rain filled dams and waterways on her property, near Miriam Vale, over the past couple of weeks.
"A lot of winters we've had in the past years have been quite dry, but that'll be plenty of feed now," she said.
Ms Andrews said it was a relief after missing out.
"I think everybody welcomed the rain after such a long dry spell," she said.
The BOM urged people to watch for warnings on the website and limit travel to avoid being caught in flash floods.
Ms Pagel said the rain was expected to ease by Sunday.
A race to harvest
Emerald farmer Renee Anderson raced to harvest her mung bean crop between last week's rain and now.
"The potential risk is that if we don't get it off then it just has more downgrades and it starts to sprout," she said.
"There will be some delays if that rain that's forecasted looks to come in."
While the rain was welcome after "seven long, hot, dry years", some farmers suffered.
"It was poor timing with harvest and with quite a few different crops around in the area that were just about to be picked," Ms Anderson said.
