From March until July 1974, "Vendetta" was again deployed to the Far East. In October, the destroyer represented the RAN at celebrations of the centenary of Fiji's cession to Britain. Following the destruction of Darwin by Cyclone Tracy in December 1974, "Vendetta" was one of thirteen RAN ships deployed as part of the humanitarian aid mission Operation Navy Help Darwin. The destroyer sailed on 27 December from Sydney, and arrived on 3 January, with shore parties primarily assigned to the Nightcliff area. The destroyer remained in the area until late January. During mid-1975, "Vendetta" operated in the Far East. In August 1975, following tensions between Indonesia and the former Portuguese colony of East Timor (which cumulated in the Indonesian invasion in December), "Vendetta", "Vampire", and the supply ship were pre-positioned in Darwin in case they were needed for evacuations of Australian citizens or Timorese refugees. Action by the ships was not required.
