Alma was the second vessel used by Henry Perdriau for his Balmain Steam Ferry operations. The building of this vessel allowed Perdriau to extend his service to Bald Rock in Johnstones Bay, Annandale.

Her engines, developing 15hp were built locally at Balmain by a gentleman named Swan. The vessel was capable of carrying horses and carriages as well as passengers which may indicate she was a punt.

Almost immediately, she had her first accident when, on the 31st of August 1856, she collided with another steamer (the Pearl). Her master, Archibald macbeth was charged with being "in breach of steamboat regulations" although the water police could not prove that he was in charge of the vessel at the time. as a result, the charges were dropped.

In the late 1870's the company and the ferries were sold to John Watson who continued to operate the service.

Alma was broken up in 1891.
