SS Melba

The SS Melba was built in 1921 as a cargo steamer to operate on the River Derwent. She commenced operations as a single-deck vehicular ferry on the Bruny Island run on December 13, 1954,^[1] with a capacity of 22 cars.^[2] She was the primary Bruny Island ferry until the arrival of the Mangana in 1961. After that date, she continued on the Bruny Island run, assisting during peak periods and when the Mangana was under repair.

In 1975, the Tasman Bridge disaster created an urgent short-term need for ferries operating across the River Derwent. The Melba, despite frequent strandings due to her deep draft, operated between Hobart and Bellerive.

Mangana

The Mangana, originally known as the George Peat, was one of two 42.06 metre-long single-deck ferries built in 1930 to operate a service across the Hawkesbury River.^[3]

After a stint operating on Auckland Harbour, the 42.06 metre long ship (now known as the Ewan W. Alison) was purchased by the Tasmanian Government in 1959. Although both the Ewan W. Alison and its sister ship the Alexander Alison were purchased from their New Zealand operators for use on the Bruny Island run, the Alexander Alison sunk on April 30, 1960 while being towed across the Tasman Sea. Seven months later, the Mangana was successfully towed across the Tasman, and commenced operations on the Bruny Island run on March 27, 1961. The Mangana was named for a Chief of the Bruny Island people, whose daughter Truganini is generally considered to have been the last full-blooded Tasmanian Aborigine.

The Melba stayed on to fill the gap left by the loss of the Mangana's sister ship.

The Mangana, with a capacity of 37 cars,^[2] was the primary Bruny Island ferry until the early 1980s, staying on as a reserve ferry for the Harry O'May until 1991.

Harry O'May

Formerly the Hong Kong ferry Man On, the Harry O'May operated the Bruny Island route in the 1980s and 90's. Its two decks greatly increased carrying capacity relative to the smaller earlier ferries.

Mirambeena

The Mirambeena began operation on the Bruny Island run in the early 1990s. Completed in 1991, it is a 52-metre two-deck ferry equipped with a Voith-Schneider propulsion system.^[3]
