The Aquarium Avenue Boat Ramp in Hemmant is a basic, single-lane concrete ramp with a floating timber pontoon that provides access to the Brisbane River via Aquarium Passage, in a riverside suburb of Brisbane.

The ramp is best suited for tinnies, kayaks, and other small vessels. It is tide-dependent, with a steep drop at the end, and the surface can be slippery when wet. The nearby pontoon is in poor condition and should be used with caution.

With numerous boats moored in the area, care is needed when navigating the water after launching. Facilities are minimal and parking is limited. The surrounding area is quiet, making it a low-key option for small-boat access to the Brisbane River.
