It was a record breaking attendance at the seventh annual Luca's Legacy clean-up with over 500kgs of rubbish removed from Mandurah's waterways.
The event is in memory of local dolphin calf, Luca, who passed away after becoming entangled in fishing line in 2019.
This year’s clean-up, which took place on October 26, spanned two sites with volunteers rolling up their sleeves to tackle litter and marine debris.
Site one, at the Dawesville Cut, saw around 230 volunteers collect a huge 390kg of litter.
Mandurah Cruises hosted site two at Creery Wetlands and Boundary Island where 52 volunteers cruised out to Mandurah's estuary islands and collected 122kg of rubbish.
This included large items like chairs, mattresses and insulation, along with broken glass, plastic, rope, plastic bags, bottle tops, sanitary items, drink bottles and clothing.
"It was heartwarming to see the range of generations, and so many juniors being involved," Estuary Guardians Mandurah said.
"We also had people come from as far away as Perth, and visitors from overseas.
"Whilst it is awful that there is so much rubbish, we are so thankful it has now been collected and can never harm our dolphins and seabirds."
