The king tide did not erode Bribie Island much further on Tuesday, after the powerful waters cut through the northern tip on Monday.
However, a Department of Environment and Science expert says it is only a matter of time before the island is permanently split in two, given the long-term erosion that has worn the island down.
DES principal coastal scientist Sel Saltmann said Bribie Island had been eroding about one metre a year as far as records went back.
“It may recover after this event, but the long-term erosion process is going to continue and it’s most likely that Bribie Island will break through between Moreton Bay and Pumicestone Passage this year and the next few years,” he said.
Caloundra Coast Guard commander Roger Pearce said the two-metre king tide did not do as much damage on Tuesday as it had done in the past three days.
“If we had another day like yesterday [Monday], there would have been another permanent opening through Pumicestone Passage, but nature is on our side today [Tuesday],” he said.
From Saturday night to Tuesday morning, the State Emergency Service received more than 1400 calls for help, with most concentrated around the state’s south-east.
In updated rainfall totals on Tuesday, Upper Springbrook in the Scenic Rim recorded 202mm in the past 24 hours, taking its total since 9am on Saturday to almost 900mm.
The Gold Coast Seaway received another 56mm in the past 24 hours, taking its three-day total to almost 190mm, while Landsborough had 16mm for a total of 195mm.
Brisbane added another 8mm overnight, taking the three-day total to 78mm.
On Tuesday, the highest rainfall total was Kandanga in the Gympie region with 26mm, while 25mm fell in Morayfield, north of Brisbane, and Sippy Downs on the Sunshine Coast had 16mm.
Bureau of Meteorology’s Pieter Claassen said a severe weather warning remained for abnormally high tides and hazardous surf, as well as a minor flood warning for the Logan River.
A flood watch remained for Fraser Island to the NSW border, however the risk of winds and rainfall was expected to ease.
“Showers and thunderstorms will continue for much of Queensland this week owing to a broad region of low pressure and high moisture across much of the state,” he said.
“Isolated locations have seen considerably higher totals with Upper Springbrook recording 953 millimetres in the last week, almost three times its monthly average.”
Mr Claassen said temperatures would warm gradually in the coming days, with some areas to reach five to eight degrees above average.
Tropical cyclone Yasa, near Fiji and Vanuatu, and Tropical Cyclone Zazu in the South Pacific were expected to intensify but were not predicted to affect Queensland, Mr Claassen said.
