Tourism in West Australia's Midwest has been dealt a blow after one business that transported visitors to the Albrohos Islands shut down and another announced a pause in operations.

Fishing charter and tourism business Abrolhos Adventures closed last week after being unable to secure a buyer.

It came just days after Geraldton Air Charter, which also services the Abrolhos Islands, announced a pause in operations while self-reported potential safety issues were investigated. 

Abrolhos Adventures co-owner Tanya Johnson said there were several factors behind the business's closure, including fuel prices and resources.

She said more tourism infrastructure would have been beneficial.

"A jetty at the islands would have made a substantial difference and a world-class elevation to our product," Ms Johnson said.

The state government has made significant investments into tourism in the area, including a $12-million commitment to visitor and management amenities.

It is spending $900,000 over three years on Geraldton's Shore Leave festival which promotes the Islands. A highlight of the festival being a luxury long table luncheon.

A 10-year management plan released in November outlined activities to support the natural habitat, cultural heritage, fishing, recreation and tourism at the national park.

More support needed

Abrolhos Adventures general manager Tori Hallgarth said she was proud of what the business had achieved over five years of operations but future ventures would need more support to remain viable.

"Geraldton needs a little bit more support in the tourism sector to be able to facilitate something like [Abrolhos Adventures]," she said.

"I hope for businesses in the future that do choose to go out to the Abrolhos Islands that there is the additional support and that they can learn from everyone else who has been doing it."

City of Greater Geraldton Mayor Shane Van Styn agreed.

"[Abrolhos Adventures] added a vibrancy and activity to Greater Geraldton and Western Australia, which will be missed," he said.

"We hope in the future we may see a return of such a venture, should public facilities be developed to better service such operations both in Geraldton and at the Abrolhos Islands."

But Midwest Chamber of Commerce and Industry chief executive Joanne Fabling said she was not concerned about the impact the loss of the businesses would have on tourism at the islands.

"The WA government is absolutely committed to eco-tourism on the Abrolhos Islands, and that’s a process which does take time," she said.

"You look at the bodies that are committed to seeing that tourism is developed in a very sustainable way on the islands."

In a statement, Tourism Geraldton Midwest (TGMW) chair Matt Rutter said there were no plans to scrap this year's Shore Leave Festival at the Islands in April.

"This year's Long Table travel options are air and own sea transport," he said.

"Ticket sales are going extremely well, and we expect similar numbers at this year's event to last year.

"TGMW firmly believes this emerging tourism offering will continue to develop for the benefit of operators and the local community."
