Have you seen the glowing water at the Pinkenba Boat Ramp? A vivid blue glow was captured at the river this August, creating a striking nighttime display as the water lit up when disturbed.

The video, shared by Brett Sarapung, shows the bioluminescent glow at Pinkenba, where it was particularly prominent during the sighting.
The display came several hours after the 6.22pm high tide, although similar sightings have been reported around both low and high tides. Bioluminescence in the Brisbane River is sporadic and can shift with the tides.
What Makes The Water Glow?
The answer lies in microscopic marine life. Bioluminescence is produced by tiny single-celled organisms known as dinoflagellates. One species associated with this type of display is Noctiluca scintillans, commonly known as sea sparkle.
Individually, these organisms are too small to see. When large numbers are present, their flashes can create the blue-green glow visible across the water. The light comes from chemical reactions within the cells. Disturbing the water can trigger brief flashes, allowing waves and movement at the surface to reveal the organisms.
Noctiluca scintillans also feeds on microscopic organisms including diatoms. Some forms contain photosynthetic symbionts, which means photosynthesis can also form part of their biology.
Queensland’s Department of the Environment, Tourism, Science and Innovation listed bioluminescence among the state’s unusual natural phenomena. The department notes that the effect has occasionally been seen in Queensland waters, including Moreton Bay and the Brisbane River.
Where Else Has It Appeared?
Pinkenba is one of several Brisbane locations where the glow has been observed in 2026. Recent sightings have included the Colmslie Boat Ramp in Morningside, as well as areas around Howard Smith Wharves and New Farm Park.
There is no reliable time or location for seeing it. Water movement and tides can influence where the glow appears, meaning conditions can vary from one location to another. The August 8 sighting at Pinkenba is one example. The glow was particularly prominent there, but the phenomenon has also been found at different boat ramps along the river.
For anyone heading out to look, patience may be required. A stretch of dark water can suddenly sparkle when disturbed, producing brief flashes of light before conditions change.
Enjoy The Spectacle Responsibly
The display is fascinating, but the river should still be treated with caution. Anyone entering the water does so at their own risk and should wash off with fresh water afterwards. Do not drink the water.
Visitors are also asked to respect locals and others enjoying the location, avoid unnecessary disturbance and take all rubbish with them.

The glow offers a rare glimpse of an invisible world beneath the surface. The organisms may be microscopic, but under the right conditions, they can turn the Brisbane River into a spectacular natural lightshow.
