Greenbank residents say their objections to a proposed white water park are based on planning reasons, not ill feeling towards the facility.
They met with mayoral candidate John Freeman, and Division 11 hopefuls Bryan Bartlett, Kath de Leon and Natalie Willcocks on Saturday to object to the location of the proposed Olympic-standard white water park.
The park is earmarked for council-owned land on the corner of Vineyard Drive and the Mount Lindesay Highway.
it would go next to 30 hectares of remnant vegetation owned by the state government.
About 50 residents turned out for the meeting.
They say the facility will impact the wildlife in the area, and use the land as a corridor through to the Boronia Bushland Reserve.
They are also concerned about historic mango trees.
Campaigners say kangaroos and wallabies gather on the land regularly.
"Those grasslands are what kangaroos feed on every afternoon," campaigner and resident Donna Olive said.
"It's not that we don't want the white water park in Logan, it's just we don't want it at this location."
"The general consensus is that it's the wrong location."
A council spokesman said the environment had been considered in the plan.
"The local significance of the mango trees and the environmental value of the biodiversity corridor have been taken into consideration in the conceptual design and we have endeavoured to keep the footprint of any development similar to that identified in the parklands design," he said.
