A new independent documentary will shine a light on the extinction of three south-west black cockatoo species facing in Western Australia.

The film project was recognised for its potential to be a change maker in its early development, winning the prestigious 2021 Brian Beaton Award for Social Impact.

Director/producer Jane Hammond said the film highlighted the plight of the Carnaby's, Baudins and Forest Red-Tailed black cockatoos and looked at ways we can reverse their decline.

"If we do nothing these iconic birds will disappear from our skies within two decades," Ms Hammond said.

"The film aims to move audiences to demand action from our political leaders to stop these beautiful creatures slipping into extinction. With so little time left to turn the situation around we need to act now.

"Filming black cockatoos has been an incredible privilege and a steep learning curve. They are very intelligent social creatures with unique personalities.

"We are losing birds to car strikes, illegal shooting, land clearing, pesticide poisoning, food shortages, nesting shortages and general habitat loss. This really is a story that needs to be told."

Joining Ms Hammond in her fight to save the black cockatoos are peak conservation organisations, the Wilderness Society and the WA Forest Alliance.

WAFA campaign director Jess Beckerling described the film as "beautiful and powerful."

"We often hear about the push of a species to the brink of extinction, but it's not always easy to grasp what that means.

"This film goes straight to the heart and is going to be a critical tool in educating and mobilising the community," Ms Beckerling said.

Wilderness Society WA campaigns manager Patrick Gardner said the film provided an evocative depiction of the threats faced by these threatened species.

"In the UN Decade of Ecological Restoration and following the Australian Government's recent commitment to halting extinctions.

"Black Cockatoo Crisis brings to light the need to urgently protect the remaining habitat for the three species of Black Cockatoos in South-West WA." Gardner said.

Paddy Cullen from the Save the Black Cockatoos Coalition said his group's calls for action from political leaders had so far gone unanswered.

"We have developed a 12-point Emergency Plan to Save the Black Cockatoos but it has been rejected by the Ministers for Forestry, Environment and Planning.

"We are hoping this film will be the circuit breaker for the Premier to step in to save these incredible black cockatoos from extinction."

It has the fiscal support of Documentary Australia and was developed with the assistance of Screenwest and Lotterywest.

Black Cockatoo Crisis, distributed by Halo Films and made by Fremantle Freelance made its world premiere at the Luna Leederville on Wednesday November 23.
