Wetlands wonderland - Bribie’s floating wetlands thriving

A thriving floating wetlands system at GemLife Bribie Island harnesses the natural power of plants to purify the water in lake dux.

Hundreds of native wetland plants grow from a flotilla of rafts made from recycled PET bottles that mimic the actions of natural wetlands. The innovative floating treatment wetlands are designed to allow aquatic plants to grow in water that is typically too deep for them.

Since installing the floating wetlands in late 2020, Lake Dux has seen a significant improvement in water quality, which in turn has also provided a diverse, sustainable habitat for pollinators, migratory birds, fish, and local wildlife.

GemLife Director & CEO Adrian Puljich said GemLife’s mission has always been to do its best to positively impact the environment, people, and society.

“At GemLife, we constantly strive to educate ourselves on environmental sustainability and work towards implementing eco-friendly systems,” said Adrian.

“The floating wetlands are considered nature-based solutions with great potential to promote several ecosystem services, such as enhancing biodiversity and water quality, and we have seen the benefits first-hand since we introduced the system to GemLife Bribie Island’s Lake Dux.”

The floating wetlands are low-maintenance and remain in the lake all year round and are anchored in such a way that they can rise or fall after rainfall or with the seasons.

Plants that are used are those most suited to waterway applications, typically native to the area and applicable to the situation. As plant growth is promoted, water and bird life are encouraged to create a revitalised natural environment.

GemLife Director of Sustainability, Renewables & Energy Mark Langdon said these man-made floating islands also help to reduce pollution.

“Floating islands are platforms that hold plants so that the roots can grow into the water and improve water quality,” said Mark.

“They act as ‘nature’s kidneys’ by removing excess nutrients and contaminants that have entered our waterways via stormwater runoff. During resort planning, our team focussed on maximising this wonderful asset for community members and ways of encouraging and promoting the natural environment.”
