Tet had a similar effect on Australian public opinion, and caused growing uncertainty in the government about the determination of the United States to remain militarily involved in Southeast Asia. Amid the initial shock, Prime Minister John Gorton unexpectedly declared for the first time that Australia would not increase its military commitment in Vietnam. The war continued without respite, and between May and June 1968 1 ATF was again deployed away from Phước Tuy in response to intelligence reports of another impending offensive. In May 1968 1 RAR and 3 RAR with armour and artillery support fought off large-scale attacks during the Battle of Coral–Balmoral. Twenty-five Australians were killed and nearly 100 wounded, while the North Vietnamese lost in excess of 300 killed.
