Storms have claimed the lives of three more people in southeast Queensland with another three feared dead.

The body of a nine-year-old girl was found on Tuesday evening after she was feared lost in stormwater drains in Brisbane.

Another body was recovered from Moreton Bay after a boating accident that is feared to have taken the lives of two more.

A third, that of a 40-year-old woman, was found in the Mary River in Gympie.

The Christmas storms had already accounted for one death on Monday when a 59-year-old woman was killed when she was hit by a fallen tree on the Gold Coast.

The body of the girl was located following an extensive search, said police, who added they do not believe there are any suspicious circumstances.

The statement added the family, from Rochedale South, “are requesting privacy at this difficult time”.

The second confirmed death followed a boat capsizing south of Green Island. Eight people were taken to hospital and a search-and-rescue operation launched involving water police vessels, police divers, volunteer marine rescue and coastguard for three people reported missing. 

The search found one body but the other two people had not been accounted for when it was suspended just before midnight. The operation will continue at first light.

The woman recovered from the Mary River was one of three swept into the water by the Kidd Bridge. One woman, a 46-year-old, managed to get to safety. Another 46-year-old woman is missing with the search due to resume this morning.

Severe weather had lashed parts of Queensland’s southeast on Christmas and Boxing Day.

At Gympie a wind gust of 100km/h was recorded on Tuesday while golf ball-sized hail was spotted at Zillmere in Brisbane’s north. 

At Jindalee in Brisbane’s southwest 62mm of rain was recorded in an hour.  

On Christmas Day storms left more than 120,000 households without power and some were still cut off with more than 800 powerlines down across the southeast. 

The Bureau of Meteorology says some further severe thunderstorms are possible on Wednesday around central and northern parts of the Queensland coast, and potentially reaching south to Brisbane.

However by Wednesday afternoon conditions are expected to ease.

Heatwave conditions in the state’s north have prompted warnings from meteorologists, with maximum temperatures across the Gulf region expected to reach the low 40s on Wednesday.
