The ferry is operated by a private sector operator under contract to New South Wales Roads and Maritime Services and is free of tolls. The crossing is 366 metres (1,201 ft) in length and takes approximately 4 minutes. The ferry operates on demand 24 hours a day, 7 days a week, with no regular maintenance closure. Two ferry boats are available at this crossing, operating on separate sets of cables, and when traffic demands it both may be in use. The larger of the two boats carries up to 24 cars, whilst the smaller one carries only 8.
The ferry is one of two cable ferry crossings in the community of Wisemans Ferry, the other being Webbs Creek Ferry, which crosses the Hawkesbury River to a point upstream of the confluence with the Macdonald River. Two other such ferries cross the Hawkesbury River proper, these being the Sackville Ferry and the Lower Portland Ferry, whilst a fifth ferry, the Berowra Waters Ferry, crosses a side-arm of the river.
The ferry is named after its founder, Solomon Wiseman, a former convict (1778–1838), who received a land grant in the area from Governor Macquarie in 1817. Wiseman established the ferry service in 1827 for the transport of produce and provisions to the convicts building the Great North Road to link Sydney with the fertile Hunter Valley. Initially located 2 kilometres (1.2 mi) downstream of its present location, the crossing was moved to its present location in 1829 when the Great North Road was repositioned and reconstructed. In 1832, the Wisemans ferry service was purchased by the government.
Until the opening of the Peats Ferry Bridge across the Hawkesbury at Brooklyn, Wisemans Ferry was on one of the main road routes north out of Sydney. However when that bridge opened in 1945, vehicular traffic along the Great North Road through Wisemans Ferry was reduced, and the crossing at Wisemans Ferry could no longer be considered to be on the main route north to Newcastle.
