However, a double-ended screw configuration was particularly difficult for the fine bows that Manly ferries required for both speed and heavy seas.

The "Binngarra-class" ferries, Binngarra (1905), Burra-Bra (1908), Bellubera (1910), Balgowlah (1912), Barrenjoey (1913), and Baragoola (1922), were designed by Mort's Dock and Engineering, initially under the guidance of former chief draughtsman Andrew Christie.

She was a near identical sister to Barrenjoey (later North Head) and Balgowlah (1912), and similar to the slightly smaller Binngarra (1905), Burra Bra (1908) and Baragoola (1922).

[3] The exorbitant cost and difficulty in replacing the large expensive steel hulled Binngarra-type vessels saw the Bellubera, along with the Balgowlah, Barrenjoey, and Baragoola retained and significantly modified.

[5] On 16 November 1936, fire broke out aboard Bellubera while she was moored at the Kurraba Point depot while workmen were repairing a steel plate on the roof of the upper deck.

[1] On 6 February 1946, her master, Captain Walter Dohrn, collapsed and died at the wheel as the vessel was making its way across the Heads towards Manly.

[8] In October 1960, Bellubera collided with the 7,000-ton Norwegian freighter Taurus but received only minor damage continuing her run to Circular Quay.

[1][8] On 28 February 1970, en route from Manly, Bellubera collided with the Australian Navy Ship, HMAS Parramatta as it was backing out of the naval depot near Chowder Bay.

Navy personnel covered the Parramatta's damage with a tarpaulin to hide it from press photographers, while Bellubera resumed her journey.

[8] She was sold in 1975 to a company named Trouble Shooter, so certain equipment could be stripped and installed into the ex-Royal Australian Navy Ton-class minesweeper HMAS Gull.

Bellubera′s English Electric diesels were removed and returned to the Public Transport Commission to support the Baragoola and North Head in service.

Bellubera was towed to sea by tug Betts Bay and scuttled off Long Reef on 1 August 1980 and today rests on her side in two pieces in 45 metres (148 feet) of water.
