On 4 March 1804, when the New South Wales Corps went into action to put down the Castle Hill convict rebellion, the locally raised Governor's Body Guard conducted reconnaissance patrols in front of the New South Wales Corps as they advanced towards the rebels, militia personnel from the Sydney and Parramatta Loyal Associations had taken over the role of guarding strategic locations to free up men from the New South Wales Corps. This unit was later disbanded in 1810, however, following the departure of the New South Wales Corps and the arrival of regular British infantry regiments, while the Governor's Body Guard was eventually amalgamated with the Mounted Police in the mid-1840s, before eventually being disbanded in 1860.
