Tickets are on sale to four exclusive tours and the next one takes place this Wednesday the 31st of May, precisely 75 years ago when the conflict came right into Sydney Harbour.

National Parks and Wildlife Service (NPWS) Discovery Coordinator, David Thompson said the award-winning tour allows people to retrace the path of the midget submarines that were part of a carefully orchestrated enemy attack.

"This exciting harbour tour into Sydney's past takes place on a historic ferry and allows people to learn about the attack that culminated in the death of 21 allied Australian and British sailors.

"By tracing the movements of the infamous submarines, people are also given an insight into the civilians and naval personnel involved in this extraordinary story.

"Part of the tour also takes place at the Royal Australian Navy Heritage Centre at Garden Island to see a view of the conning tower of one of the submarines.

"With their curiosity satisfied with stories, guests are then treated to afternoon tea on Fort Denison, part of Sydney Harbour National Park.

"It's a perfect day out for any history buff or for those looking for an interesting insight into the history of our beautiful city," Mr Thompson said.

Tours cost $79 for adults and $74 for concession/child and take place from Cadman's Cottage forecourt at The Rocks from 10am to 1:30pm on the 31st of May, 4th, 18th and 25th of June.
