''Kummulla's
official trials were on 15 January 1903 where she attained 11 knots. The next day, The Australian Star newspaper described her as "the prettiest steamer of the Sydney Ferries Limited fleet of modern harbour steamers". The Sydney Morning Herald described her as "distinct advance upon any of the vessels running in the Mosman service" and "elaborately furnished". Kummulla'' was built for the Mosman Bay service and also served the Circular Quay to Lavender Bay run. In 1932, the
Sydney Harbour Bridge was opened, and Sydney Ferries Limited's annual patronage dropped from 40 million to about 15 million. As part of economy measures, older and/or most of the larger steamers were put up for sale.
Kummulla was laid up for sale in 1934. Her engine was removed in 1935, she was hulked, and her hull sold for scrapping in 1939. File:Sydney Ferry KUMMULLA in Mosman Bay ca 1903.jpg|As a new ferry,

Incidents • On 30 August 1909,
Kummulla collided with steam launch,
Vivid, causing considerable damage to both vessels. ''Kummulla's
steering was disable and there were fears that Vivid
might sink, with the master of the Vivid'' found to be at fault. • In July 1911, she collided with Sydney Ferries Ltd ferry
Kangaroo between Lavender Bay and Dawes Point. • She collided with
Vaucluse in July 1919 and was out of service for several weeks for repairs. In August 1921, she struck the vehicular ferry
Benelon in thick fog. ''Benelon's
steering gear and bulwarks were damaged. Shortly after on the same day, with a thick fog diminishing visibility, the Benelon
soon collided with the ferry Woollahra''. • In 1927,
Kummulla was the first vessel to arrive on the scene of the
Greycliffe disaster. The Watson's Bay ferry,
Greycliffe, had been struck by the liner
RMS Tahiti cutting the ferry into two and sinking it. ''Kummulla's
crew diverted her from her run to Mosman and rescued passengers from the water, a number of whom were injured. Those rescued on Kummulla'' were taken to waiting ambulances at Mosman Bay. ==See also==
