Low-lying Rockhampton suburbs brace as Fitzroy River nears peak

Flood impacts are being felt across low-lying parts of Rockhampton, even as authorities downgrade expectations for the peak of the Fitzroy River following heavy rainfall from ex-Tropical Cyclone Koji.

The Bureau of Meteorology (BoM) has revised its forecast, now expecting the Fitzroy River to peak at 7.5 metres on Thursday morning, lower than the earlier prediction of 7.8 metres earlier in the week.

Emergency planners say the revised outlook is likely to reduce the overall impact on the city. About 280 properties are now expected to be affected to varying degrees during the moderate flood event, down from earlier estimates of up to 480.

While river levels continue to rise, meteorologists say conditions across central Queensland should remain relatively stable in coming days. Further shower or storm activity is possible inland, but is not expected to significantly worsen flooding in the Fitzroy catchment.

As of Wednesday morning, the Fitzroy River gauge in Rockhampton's CBD measured 6.5 metres and was forecast to reach 7 metres during the day, officially entering minor flood levels.

Rising waters have already forced the closure of riverside facilities, sporting fields, car parks and pedestrian walkways, as well as several local roads including Lakes Creek Road.

Council modelling indicates that some homes may experience water above floor level, while historical flood data suggests suburbs such as Depot Hill could become nearly isolated. Low-lying sections of Port Curtis, Fairy Bower and Gracemere are also expected to see inundation.

Deputy Mayor Drew Wickerson urged residents to remain cautious despite the improved forecast.

"We want people to remain vigilant - we don't relax for one moment," he said. "But this event is nothing like the major floods Rockhampton has experienced in the past."

Authorities continue to monitor river levels closely and advise residents in flood-prone areas to stay informed and prepared as the Fitzroy approaches its peak.
