The WA Government has announced a $33 million boost for the state’s premier tourist destination, Rottnest Island.

The island is receiving the funds to upgrade its attractions and infrastructure, with $17.2 million coming from the Federal Government’s national “tourism icons” program.

The projects to be funded include the refurbishment of a WWII building, which will be turned into a backpackers’ retreat.

“It will be an opportunity for young adults I think to get affordable accommodation. So they can make a bit of noise and enjoy themselves,” Tourism Minister Paul Papalia said.

A total of $700,000 will go to new beach toilets, showers, seating areas and landscaping, while $2 million will be spent on the revitalisation of the Wadjemup Hill lighthouse vicinity.

A new transport hub and refurbishments of the lighthouse keepers house have been funded too, as well as $600,000 for signage to help visitors make their way around the island.

The state government’s $16.2 million will go towards logistics - a new fuel jetty and barge landing – to ease pressure on the Thomson Bay's ferry terminal.

There are also safety upgrades that were pledged after the Rottnest Island Authority and state government copped criticism when an ageing Army jetty collapsed and three people were seriously injured.
