Rocky Bluff Battery and Township, Historic mining settlement and battery ruins in Watsonville, Mareeba Shire, Australia.

Rocky Bluff Battery is a historic tin processing site along the Walsh River in Watsonville featuring preserved tramway formations, processing stamps, and a stone weir across its grounds. The location encompasses roughly 4 hectares and displays the remains of early-1900s mining infrastructure.

Tin was found at Rocky Bluff in 1883, but work began after the North Queensland Tin Mining Corporation took leases in 1900 and passed them to the Adelaide-based Stannary Hills Mines and Tramway Company. The battery opened on 6 May 1903 as "Jumping Moses", closed that June when the mortar box shifted, and was rebuilt in 1905 with new stamps and a Krupp ball mill. John Darling and Company reopened it in 1912; it ran into the mid-1920s and the tramway was dismantled in 1926.

The settlement developed as a mining community with a school, hotel, and shop that drew electricity from the processing operations. These facilities reveal how daily life centered around the mine's needs.

The site is reached via the former Stannary Hills–Rocky Bluff tramway formation, with a ropeway descent of about 190 metres to the battery. The four terraced levels are separated by high rock-face retaining walls above the Walsh River, so expect steep, uneven ground and wear sturdy footwear. The stone weir and township sites in the river flat and gully are best located before walking in.

Bricks for the battery were carried in on the Stannary Hills tramway, then lowered about 190 metres down the hillside on a rope tramway to the site beside the Walsh River. Sand and gravel were carted uphill from the river for construction. The township's main streets were so steep that no cart, wagon or buggy ever entered them.
