The 2022 tidal breakthrough on Bribie Island has dramatically reshaped the coastline, creating challenges for Surf Lifesaving Queensland and sparking urgent concerns about the health of local ecosystems.

Environmental experts warn the breakthrough—caused by unusually high tides and severe weather—could lead to irreversible environmental damage if not monitored closely.

The Caloundra Residents Association (CRA) is urging local leaders to prioritise environmental stewardship and infrastructure improvements in areas bordering the Pumicestone Passage to “protect both the natural landscape and regional economic opportunities”.

A spokesperson from the Department of Environment and Science (DES) said northern Bribie Island had a long history of coastal erosion.

“In the early 1970s, the entrance to Pumicestone Passage was located much further south, near the new breakthrough,” the spokesperson said.

“Much of Bribie Island is a national park, and the Pumicestone Passage lies within a marine park conservation zone and is listed as a Ramsar Site of international importance.

“A key management principle for such areas is to maintain them as close as possible to their natural state.”

A Ramsar site is classified as a wetland of international importance as per a convention declared in 1971 to protect the conservation and sustainable use of certain coastal areas.

CRA President Craig Humphrey said Bribie Island’s ecosystems were vital, not only for local biodiversity, but also for the economic stability of surrounding areas.

“Sustainable tourism and responsible development are essential for our region’s future,” Mr. Humphrey said.

“If we fail to act now, we risk losing both our natural assets and the economic opportunities they provide.”

With residents increasingly concerned about the impacts of climate change and inappropriate development, Mr. Humphrey believed this was a “pivotal moment” to protect the passage.

“The urgency is clear – delays in action could cause permanent damage to both the Pumicestone Passage and surrounding coastal assets,” he said.

“As the election draws near, the focus shifts to whether candidates will rise to the challenge and champion critical initiatives that ensure a sustainable future for Bribie Island and the 4551 region.”
