Ballast Point is a two-hectare sandstone neck of land jutting into Sydney harbour, high above a deep water frontage on the eastern extremity of the Balmain peninsula. Its name probably comes from rockfalls at the bottom of the outcrop which provided ballast for unladen ships.
George Cooper, the Comptroller of Customs at Sydney, bought most of the land fronting Waterview Bay in 1840, including Ballast Point. These grandiose purchases were financed by mortgages which he attempted to service by selling land in building lots. The economic climate ensured a slow return and his mortgagees soon foreclosed. Declared insolvent in 1842, he was dismissed from his post. In 1852 Ballast Point was then sold to Thomas Perkins, a merchant at George Street, Sydney, who was then living in Pembroke Villa located on Johnston Street in Balmain. By 1864 Perkins had built and occupied Menevia, a large two-story sandstone villa almost in the centre of the site. The house remained in the Perkins family until purchased in 1928 by the Texas Company (Australasia), later Caltex Australia. The house was soon demolished and the site converted to an oil terminal.
The land, however, with minor waterfront reclamations, has retained its original shape. Over time the oil company built 30 storage tanks at Balmain terminal, as it became known, and for many years petrol was stored there. The frequent movement of trucks on local streets made life unpleasant for residents. From 1938 the Balmain terminal housed the only grease plant in Australia. Petrol storage ceased when the company's refined oil terminal opened at Banksmeadow, Botany Bay. In more recent years, Balmain terminal supplied bunker fuel and lubrication to ships in Port Jackson.
In 1994 Caltex released plans to redevelop the site for a mix of medium-density residential use, community facilities and public open space. Supported by Leichhardt Municipal Council, strong resident action intensified from 1997 when Caltex sold the site for development, with a provisional completion date of 2005.
In response to a campaign by residents, the Sydney Harbour Foreshore Authority, on behalf of the state government, took over the site for use as public open space in 2002, under the New South Wales Land Acquisition (Just Terms Compensation) Act 1991.
I think the site rehabilitation has been nicely done, with some leftover remnants of the industrial use remaining so we can see what it was used for in the past. I encourage you to take a stroll past GZ and explore the rest of the park to see how former industrial sites can be returned to the people and some of the other interpretative signs around the place. Note the signs state the park is only open from 6am-6pm, but there aren't any gates.
As for the cache, it's magnetic and hidden under then up. Due to the original Sistema hide poking out and being muggled, it was replaced by a mint tin, but now an Aldi version of a Berocca tube. I don't like hiding small ones like this, but at this spot it makes sense for the hide.
