HUNDREDS of people from all over south-east Queensland met at the waterfront GJ Walter Park, Cleveland to celebrate World Wetland Day on the weekend.
It includes 3600 units and a marina in a wetland area at Toondah Harbour in the Moreton Bay Marine Park.
A Redlands2020 spokeswoman said visitors saw 13 different species of wader birds feeding on the Toondah wetlands, including the endangered eastern curlew.
Visitors listened to a range of speakers, including The Moreton Bay Foundation's Andrew Davidson who spoke about wetlands and biodiversity and the need to protect such areas.
"They also used the time to paint bright banners and signs that will be used at future events to oppose the Toondah Harbour development," the spokeswoman said.
Musicians Troy Robbins and Simon Ball entertained the crowd.
