To mark the centenary of the sinking of the Titanic, Sydney's Australian National Maritime Museum is holding an exhibition about the doomed voyage.

Remembering Titanic - 100 Years will present the history of the ship from construction to its fateful sinking on April 15, 1912 and its rediscovery.

The exhibition will concentrate on the human stories behind the disaster and features replica objects, ship models, memorabilia, newspapers and graphics.

"We've pulled out some of the lesser-known human stories from Titanic," National Maritime Museum communications manager Shirani Aththas told AAP.


"We tell the stories of many people - from the junior wireless operator, Harold Sydney Bride, through to the passengers on board, including two little boys known as the Titanic orphans."

The exhibition will also look at the impact of the Titanic on popular culture from books to films, culminating in the new release of Titanic 3D.

Nine costumes from the film Titanic, including those worn by Kate Winslet and Leonardo DiCaprio, will be on display along with props, such as a hand mirror, a life jacket and a life ring.

The exhibition will also tell the story of the "unsinkable" Molly Brown, played by Oscar winner Kathy Bates in Titanic 3D.

The RMS Titanic, on a voyage from Southampton to New York City, sank after striking an iceberg, resulting in the loss of some 1500 lives.


The Australian National Maritime Museum, Darling Harbour, is open daily from 9.30am to 5pm.

Remembering Titanic, runs from March 29 until November 11. Entry is included with general admission to the museum: $7 adults, $3.50 child/concession, $17.50 families.

The museum is holding a series of events on the anniversary of the sinking, April 15, including children's craft activities, a Titanic-themed movie marathon featuring the 1958 classic A Night to Remember, and an evening lecture with maritime historian Peter Plowman.

A Fateful Feasts event will also be held on May 20 with gastronomy lecturer Diana Noyce discussing the food served on the ship.
