Constant Creek is a tidal waterway located in the Mackay region of Queensland, situated at approximately -21.012477, 149.001858. The creek connects to three other systems and opens toward the Cape Hillsborough area, giving it a broader network character typical of coastal Queensland tidal creeks.

A public boat ramp provides access to the system. The ramp requires careful navigation, particularly at low tide — approximately one metre past the ramp's rock wall marks the edge of the ramp structure, which can pose a hazard for those unfamiliar with the site. Observing other users launching before attempting the ramp for the first time is advisable. As a tidal system, water levels and currents shift significantly with the tide, and exploring the creek at low tide first to understand the layout and shallow areas is recommended before paddling at higher water.

The most significant safety consideration for anyone on the water here is crocodile presence. Constant Creek is known habitat for large saltwater crocodiles, and paddlers must exercise appropriate caution at all times — this includes avoiding entering the water and being alert near the banks and shoreline. Crocodile awareness is standard practice for any tidal system in Central and North Queensland, and Constant Creek is no exception.
