AUSTRALIA'S newest medical ship is in Mackay.

The former Fantasea Cruises vessel, once used in the Whitsundays to carry tourists to the reef, now has a new purpose.

Next year the MV Ammari is scheduled to venture into Papua New Guinea's most isolated seas and rivers, where it will deliver life-saving medical, training and building services.

But before then, it requires a refit to complete its transformation into a floating clinic.

The ship berthed at Mackay Harbour yesterday and residents are welcome to go onboard for free tours.

Those who are willing can learn how to get involved or donate to the mission.

Visitors can experience Pacific Island culture and learn how to help our nearest international neighbours, Papua New Guinea.

The ship is run by Youth With a Mission (Y-WAM) whose motto is Overcome the Impossible.

During their two-day stay in Mackay, the crew is collecting soap, toothbrushes, toothpaste, spectacles and sunglasses for people in Papua New Guinea.

Spokeswoman Anna Scott said donations of basic items could make a real difference.

"Personal hygiene equipment goes a long way in preventing medical conditions," she said.

"If people have any of these items, they should bring them along."

Y-WAM has raised $1.5 million so far to buy the $6.5 million vessel as part of a lease- to-buy agreement.
