British Military Intervention on the Frontier

British military involvement in colonial frontier violence was episodic and generally small-scale, not a continuous military campaign. At Appin in 1816, roughly 70–85 soldiers were divided among three separate detachments, rather than operating as one combined force. At Bathurst in 1824, about 75 soldiers were likewise deployed in separate parties across the district, not concentrated as a single body. Other identifiable interventions were smaller again, including about 10 soldiers at Pinjarra, around 23 on the Nunn expedition, and 19 at Port Lincoln. 

​

The major numerical outlier was the 1830 Black Line in Van Diemen’s Land, when about 550 British troops formed part of a temporary force of roughly 2,200 soldiers, police, settlers and convicts. But the Black Line was a coordinated sweep intended to capture or drive Aboriginal groups from the settled districts. It was not itself a proclamation of war.

Taken together, the record shows occasional military intervention for punishment, protection, policing support and operations under martial law — not a sustained British military campaign across Australia.
