The decision, made on September 17 and published on Monday, confirms the Australian government's original view that the project is "not a controlled action," meaning it will not require a full environmental impact statement provided strict conditions are met.
The Redlands-based Community Alliance for Responsible Planning (CARP) had appealed to federal Environment Minister Murray Watt in June, arguing that the shallow water table beneath the site was vital to trees that nourish protected koalas. CARP president Lavinia Wood said at the time that expert evidence showed the industrial-scale whitewater centre could be devastating to the local koala habitat and that full assessment was needed.
In his decision, acting National Environmental Protection Agency Queensland branch head Mark Hall upheld the government's earlier position. On Monday, Wood said she was "exceedingly disappointed."
"We thought the scientific evidence would convince the minister to declare a controlled action and require an environmental impact statement to properly study the land," she said.
