Slacks Creek is not the Logan River's biggest tributary but it links some of the city's busiest suburbs to the river. It's the creek you see when you find the "Logan Eye Key? Ah!" cache, or drive over Compton Road. Slacks Creek has lost much of its naturalness over time as homes, shops and factories have sprung up on surrounding lands and reshaped the little streams that feed its waters.
.
Today it struggles with pollution and erosion as more and more unfiltered storm water gushes in from urban areas after rain. Yet the catchment still supports large wildlife habitat areas and pockets of healthy bush land.
The Slacks Creek Environmental Park is kept in its natural state. In times of heavy rains, it is a natural flood plain that stores water run-off.

Scrubby Creek runs through this part of the park into Slacks Creek just north of the Loganlea Road Bridge over Slacks Creek.
The cache you are seeking is not in the bush.
