 While garrisoning the Australian Colony of Victoria in 1854, detachments from the regiment, the 40th Regiment of Foot and colonial police, suppressed the Eureka Rebellion, by gold prospectors at Ballarat.The regiment was not fundamentally affected by the Cardwell Reforms of the 1870s, which gave it a depot at Gibraltar Barracks in Bury St Edmunds from 1873, or by the Childers reforms of 1881 – as it already possessed two battalions, there was no need for it to amalgamate with another regiment.Under the reforms the regiment became the Suffolk Regiment on 1 July 1881.
