ORRCA is the most experienced and successful whale rescue organisation in Australia. Every year ORRCA trains many members of government agencies and ORRCA Members in marine mammal rescue.

ORRCA is also involved with the protection and welfare of seals, sea lions, dolphins and dugongs. We also work with government authorities and other groups with marine mammal rehabilitation and release. ORRCA's input is also sought when legislative bodies are amending existing laws or introducing new ones. We assist with monitor and give advice on marine animal entanglements.

Everyone is a volunteer and is the only wildlife carers group in New South Wales licensed to be involved with marine mammal rescue, rehabilitation and release. We operate as a non-profit organisation and have charity status.

ORRCA operates a 24/7 Marine Mammal Hotline. This is staffed by volunteers and keeps members, government authorities and interested members of the public informed of marine mammal emergencies, incidents and sightings. These incidents are not only in New South Wales but often in other states or even other countries.

ORRCA receives limited government funding and grants but otherwise relies on income from memberships, donations and workshops to keep the hotline and the organisation functioning.
