Western Australia's Kimberley region is preparing to host one of the world's longest total solar eclipses, with millions of dollars set to be invested into infrastructure and public safety ahead of the rare event in 2028.

The total solar eclipse will take place on July 22, 2028, with the East Kimberley area expected to attract thousands of visitors from around Australia and overseas who are eager to witness the spectacle.

The eclipse will begin over the Indian Ocean before crossing over to the Kimberley, where some areas are predicted to experience more than five minutes of totality.

The East Kimberley region in particular is expected to experience the longest duration of totality anywhere on the Australian continent, reaching up to five minutes and 10 seconds.

The WA government has announced $24.6 million in funding from 2026-27 through to 2028-29 to help prepare the region for the influx of visitors.

The investment will include upgrades to camping sites, water and wastewater facilities in Kununurra, telecommunications infrastructure and public safety services.

The funding is also expected to create opportunities for Aboriginal businesses and tourism operators throughout the region.

Kimberley MP Divina D'Anna said the eclipse would help showcase the region on a global stage.

"The Kimberley is set to host one of the world's longest total solar eclipses, drawing visitors from far and wide," Ms D'Anna said.

"This is an opportunity to showcase the beauty and uniqueness of the Kimberley to the world.

"The Cook Government is proud to be investing in critical infrastructure upgrades and public safety services to prepare the region for this extraordinary event."

A proposed public viewing site is also planned along the Great Northern Highway within the eclipse's line of totality.

WA's minister for Regional Development and the Kimberley, Stephen Dawson, said the region would offer a unique viewing experience.

"The East Kimberley is the best place in the world to see this rare astrological phenomenon, with the longest period of totality, clearest skies, and dramatic landscapes," Mr Dawson said, adding that the state government is "funding key infrastructure and services to enable visitors from across the country as well as from overseas to visit the region for this unique experience".

"The event is a once-in-a-lifetime opportunity for residents and visitors, as well as providing an economic boost to local communities and businesses."

Visitors are already being encouraged to plan ahead, with astronomers and eclipse enthusiasts from around the world expected to travel to the Kimberley.

July is considered one of the best times to visit the region, with dry-season conditions typically bringing clear skies and mild weather.

Travellers are also encouraged to immerse themselves in Kimberley culture and experiences with Traditional Owners while visiting the region.

The eclipse path will continue across the Northern Territory, Queensland and New South Wales before crossing over Sydney and travelling towards New Zealand.

While the Kimberley will experience totality, partial eclipse viewing will also be visible in other parts of Australia.
