Visitors are getting the chance to experience Boston Island off of Port Lincoln in an initiative that involves local tourism operators.
Boston Island Ferry has been operating since before Christmas to provide visitors with a closer look at the 960 hectare island.
The Davis family have owned the island since 1954 and are now working with tourism operators Adventure Bay Charters, Australian Coastal Safaris and Oceanic Victor to open up the island to the public.
Hugh Davis has been working with the tourism operators and said there was an amazing opportunity for tourism and was excited to work alongside the quality local tourism operators.
"My father Peter Davis turns 80 next year and said if I wanted to have a crack at it I should have a go," he said.
"It was an opportunity I couldn't pass up, I'm really passionate about the island and Port Lincoln.
"I'm all about partnerships and working together with locals and it's within everyone's interests to make it successful."
Mr Davis said the family was still committed to conservation on the island, having done a lot of re-vegetation over the year.
He said with no foxes or cats on the island, it had also become a sanctuary for many bird species including sea eagles, hooded plovers and little penguins.
The ferry service has been operating since before Christmas, taking place twice a week on Fridays and Sundays.
Matt Waller of Adventure Bay Charters said more than 100 people have already visited the island who have enjoyed activities such as guided mountain bike tours, guided walking tours or just having a picnic on the beach.
He said the island provided the opportunity for people to explore, learn the island's history or just relax and enjoy the natural surroundings.
"Boston Island is unique in that it's there and it kind of feels like we own it so the opportunity to go out there and touch it is pretty cool," he said.
"It's very rare that you get an opportunity to build an island destination from scratch for the modern day and for the modern market."
Mr Davis said this initiative was still in its early days but there were possibilities of further tourism opportunities, such as showcasing local produce.
"There's so much to showcase in Port Lincoln and if we can do it here it would be great," he said.
"The future for me is to start getting into tourism in partnership with good operators.
"I'm really excited to be back in Port Lincoln, excited to be working with local businesses and to try to make this all happen."
Captain Matthew Flinders and his crew were the first Europeans to step foot on Boston Island in 1802.
H.P. Davis of Hamilton Downs Station, Alice Springs bought the island in 1954 at a cost of £49,200.
