On Sunday 29 June 2025, ORRCA (the Organisation for the Rescue and Research of Cetaceans in Australia) will host its 26th annual Whale Census Day, calling on coastal communities across the east coast to take part in one of the country’s longest-running citizen science initiatives.
With the humpback whale migration season now underway, more than 40,000 whales are expected to pass along the New South Wales coastline this winter – a powerful symbol of marine conservation success. By participating in ORRCA’s Census Day, members of the public play an important role in documenting this migration and contributing valuable data that supports the protection and welfare of these extraordinary animals.
In 2024, ORRCA recorded 113 registered locations along our coastline as volunteers turned out to observe and record whale activity. ORRCA now invites individuals, families and community groups to come out for the count once again in 2025 to experience one of the world’s great migrations first-hand.
ORRCA President Ashley Ryan comments: “Census Day is a unique opportunity for Australians to come together in support of marine conservation. Whether you’re a seasoned observer or a first-time participant, every whale sighting contributes to a broader understanding of their movements, behaviours, and habitat use.”
“The citizen science data we collect on this day complements the formal research conducted by our ORRCA team throughout the year. It also helps us assess which vantage points are most effective in varying weather conditions - crucial information that informs our rescue and response operations. It’s a fantastic way to connect with nature, contribute to conservation and celebrate our incredible ocean travellers.”
The value of this synchronised observation effort lies in its scale and accessibility. In particular, land-based whale watching allows for non-invasive monitoring of whale behaviour, offering a unique and respectful way to engage with the natural world while also maintaining safe social distancing.
To participate, members of the public are encouraged to register their own location or find their nearest official ORRCA census site by visiting www.orrca.org.au/census. All sightings throughout the day are recorded digitally using an online reporting system, and further details will be provided to registered participants ahead of the day.
As a fully volunteer-operated organisation, ORRCA plays a critical role in the rescue, research and welfare of whales, dolphins, seals and dugongs in Australian waters. Public engagement through events like Census Day is essential to the continuation of this work. Report any injured, entangled or stranded marine mammals to the ORRCA 24/7 Rescue Hotline on (02) 9415 3333.
Together, let’s make every whale count.
