It fought in the Battle of N'zoth. During the battle, six warships, the Thunderhead, Aboukir, Fulimnant, Banshee, and Garland were destroyed within a short period of time. The Ballarat moved forward to cover the gaps when it was heavily hit by a Yevethan Aramadia-class thrustship. It was hit by a salvo of proton torpedoes in the forward section of Flight Deck Four and the ensuing chain reaction of detonations destroyed three squadrons of launching X-wings and E-wings. It survived the Battle of N'zoth, albeit heavily damaged.
The Ballarat commanded a task force of twenty-one warships, which included the Majestic-class heavy cruiser Mandjur.
