Blackmans Bay, TAS
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Blackmans Bay is a coastal suburb just south of Hobart, part of the Kingston–Blackmans Bay urban area that forms a satellite town of the Tasmanian capital within the Kingborough municipality. It takes its name from James Blackman, who occupied land here in the 1820s. The suburb curls around a popular sandy beach, at the northern end of which a sea-carved blowhole has eroded into a dramatic rock arch — by local account first noticed when James Baynton tracked his lost dog to its base. Southward, rocks lead out to Flowerpot Point, a favoured fishing spot, while the Suncoast Headlands track follows the clifftops and a steep path drops to fossil-studded Fossil Cove. Kingston Beach lies immediately to the north.
