You made a difference

More than 1,100 people volunteered to become Reef scientists and helped collect over 18,000 data points from coast to coral to contribute to citizen science programs throughout October’s ReefBlitz event, with some surprising finds amongst them.

A rare flamboyant cuttlefish was among the 398 marine sightings uploaded to Eye on the Reef in October.

The stunning cephalopod was spotted by ReefBlitzers in Moreton Bay – a rare find according to the experienced divers and citizen scientists who encountered it. 

But don’t be fooled by its good looks. This cuttlefish is extremely venomous. In fact, its bright, colourful display is meant as a warning!

Reef recovery bright spot

ReefBlitz’s people powered snapshot of the Great Barrier Reef also revealed that a popular tourist spot near Cairns is showing positive signs of reef recovery.  

Reef Check Australia led a survey to a long term monitoring site at Moore Reef, revisiting the location where they observed more than 70% of the coral bleached in April this year. 

Six months later the team reports that previously bleached anemones had regained their colour, just 10% of the coral population now showed signs of bleaching, and only 5% of corals had died. 

This valuable information has been shared with other Reef scientists and managers.

Keep an Eye on the Reef

Report your Reef sightings! The observations, photographs and video recordings help the Great Barrier Reef Marine Park Authority to build knowledge about the diversity, abundance, habitats and range of marine animals.

Watch Coral Colour

Capture information about coral colour! Order a Coral Health Chart to compare colours of bleached and healthy corals. Share your findings about coral colour and growth form on the CoralWatch database. Order your free Coral Health Chart from CoralWatch

Manta Ray Citizen Science

Match a Manta

Share your manta photos! Every manta has a unique spot pattern on its belly. Submit a photo or video of the underside of a manta ray to help the team at Project Manta identify and track individuals along the east coast of Australia.

Rhincodon Typus

Report unusual sealife

Do you regularly visit a local area? If you spot any uncommon marine life, share your photo with the Redmap team for identification. Your information can help map species range changes.

Beach clean-up

Clean up the Coast

Share your coastal (or underwater) clean-up findings. Your data can help Tangaroa Blue track debris to the source.
