It was said to have covered a five acre square. The site has a range of surviving features scattered on private and public land on either side of Taronga Road. These features are in varying condition and include sandstone quarries, foundations and retaining walls. stone washing tank, a stone boundary wall, a well, and a brick making area including the remnants of claypits and brick clamps. The only surviving related structure is Acton built in 1842 nearby on the Channel Highway, which was used as a residence for the Superintendent of the Probation Station.
At the station, the convicts were housed in purpose built dwellings along the ridge of Taronga Road and slightly down the north face. The station initially consisted of mainly timber buildings. In 1843, the buildings were noted as being of “ a most miserable description”. A number of new buildings were built in 1843 and these were made largely of sandstone and brick. Many of the materials used to build the station were sourced locally. Other materials were bought by sea and bought up to the station site from a landing below the nearby Alum cliffs via a track.
By 1843, the station is reported as consisting of the Superintendants House (Acton), a cook and bakehouse, two mess rooms, separate apartments for the convicts, solitary confinement cells, a track from the landing at the beach, a well, and a water tank for washing. It is presumed there was also a number of houses & barracks for the various officers & free men working at the station. There were also sawpits, quarries and a brick making area known as the Brickfields.
Work continued slowly during the next three years to bring the barracks up to its full complement. During the 1844-45 period, the station housed its greatest number of convicts, at its peak some 300 men and 67 staff.
Apart from the superintendants house, the most readily viewable remaining part of the station is the Brickfields brick making area. The Brickfields track has been constructed to provide an opportunity for pass through the site of the brickworks which provided the convicts with work and was predominately used to provide materials for the construction of buildings for the station.
The track has been constructed to protect the remaining relics in the heritage listed site with visitors utilizing a raised walkway in order to view the location of the original brick kilns and brick rubble still present. Bricks, after their firing in the kilns, were transported via a path across the creek travelling north around the ridge to the main station site, located at the end of what now is Taronga Rd.
After the road to Brown's River was finally completed in 1845, the station became a hiring depot and its numbers declined. By the next year it housed only 85 men, with a mere 43 convicts available for road parties. Numbers continued to decline and by 1850 the station was empty and left to decay.
