In the 1860s, Rottnest Island's Salt Lakes became a grim prison for Noongar people, forced into chain gangs to harvest salt under brutal overseers known as the Salt Keepers
Rottnest Island — The Salt Keepers' Conspiracy
You are Fanny Balbuk, a Noongar Aboriginal prisoner on Rottnest Island in 1845, seeking to thwart a conspiracy that threatens its future.
Your quest begins at the Salt Store,
Uncover the forgotten secrets of Rottnest Island, where salt and stone still hold the whispers of a convict economy.
The story that haunts this land
Your adventure begins at the Salt Store, built in 1854 to house salt from Rottnest Island's salterns. This 10m x 6m limestone building, restored in 1992, was the heart of an industry that supported the island's convict economy from 1839 to 1931. It is here that the first clues of a conspiracy are revealed, hidden among the traces of a vital trade that marked Western Australia's historical heritage. Every stone of this warehouse, listed on the Register of the National Estate, holds the memory of the efforts of Aboriginal prisoners and the guards who watched over these precious reserves.
Continue your investigation towards the Chapel on Rottnest Island, an Anglican church erected in 1845 by convicts under the supervision of Reverend Clapperton. This 12-meter-long structure is the oldest church still in use in Western Australia, although it was closed in 1885 after the end of the penal colony. The walls of this chapel, reopened for occasional services, resonate with the prayers and secrets of the men from Governor James Stirling's era. It is in this place of contemplation that the conspirators may have exchanged their messages, away from the prying eyes of the historic Settlement.
Your journey then takes you to the Hospital Site, a complex of stone buildings constructed in 1887 to treat prisoners and staff of the Rottnest prison. Partially demolished in 1931, this archaeological site, managed by the Rottnest Island Authority since 1917, was a place of suffering but also of confidences. The remains of the 15-bed main ward may hold hidden notes or forgotten objects by those who sought to foil the guards' maneuvers. Exploring this site, a State Heritage Place 1992, is to probe the hearts and minds that shaped the history of Rottnest Island.
Ascend to the Vincent Lookout, a 12-meter-high observation tower erected in 1900 and named after Governor Sir James Vincent. Restored in 1980 for the island's centenary, it offers panoramic views of the island's south and the Indian Ocean. It was from here that the guards monitored movements on the island, and it is also a strategic point to observe hidden signs in the landscape. You might discover coded signals or visual markers left by the conspirators to communicate across this national conservation area.
Your quest concludes near the Bathurst Point Lighthouse, a 15-meter-high stone lighthouse built in 1896 and operational until 1917. One of the island's oldest structures, this classified heritage site is accessible on foot. It is here, facing the immensity of the ocean, that you will piece together the final parts of the puzzle. The secrets of the salt guardians, the intrigues of the Rottnest Island penal colony, and the fate of Aboriginal prisoners like Fanny Balbuk are revealed. Your interactive visit to Rottnest Island will have immersed you in a little-known chapter of Western Australia's heritage, offering a deep understanding of the events that shaped this island.
