 on 25 – 26 October 1950 and at Chongju on 29 October 1950 . North Korean casualties were heavy , while Australian losses included their commanding officer , Lieutenant Colonel Charles Green , who was wounded in the stomach by artillery fire after the battle and succumbed to his wounds and died two days later on 1 November . Meanwhile , during the last weeks of October the Chinese had moved 18 divisions of the People 's Volunteer Army across the Yalu River to reinforce the remnants of the KPA . Undetected by US and South Korean intelligence , the 13th Army Group crossed the border on 16 October and penetrated up to 100 kilometres ( 62 mi ) into North Korea , and were reinforced in early November by 12 divisions from the 9th Army Group ; in total 30 divisions composed of 380 @,@ 000 men . 3 RAR fought its first action against the Chinese at Pakchon on 5 November . The fighting cost the battalion heavily and despite halting a Chinese division the new battalion commander was dismissed in the wake . Following the Chinese intervention , the UN forces were defeated in successive battles and 3 RAR was forced to withdraw to the 38th parallel .   A series of battles followed at Uijeongbu on 1 – 4 January 1951 , as the British and Australians occupied defensive positions in an attempt to secure the northern approaches to the South Korean capital . Further fighting occurred at Chuam @-@ ni on 14 – 17 February 1951 following another Chinese advance , and later at Maehwa @-@ San between 7 – 12 March 1951 as the UN resumed the offensive . Australian troops subsequently participated in two more major battles in 1951 , with the first taking place during fighting which later became known as the Battle of Kapyong . On 22 April , Chinese forces attacked the Kapyong valley and forced the South Korean defenders to withdraw . Australian and Canadian troops were ordered to halt this Chinese advance . After a night of fighting the Australians recaptured their positions , at the cost of 32 men killed and 59 wounded . In July 1951 , the Australian battalion became part of the combined Canadian , British , Australian , New Zealand , and Indian 1st Commonwealth Division . The second major battle took place during Operation Commando and occurred after the Chinese attacked a salient in a bend of the Imjin River . The 1st Commonwealth Division counter @-@ attacked on 3 October , capturing a number of objectives including Hill 355 and Hill 317 during the Battle of Maryang San ; after five days the Chinese retreated . Australian casualties included 20 dead and 104 wounded .   The belligerents then became locked in static trench warfare akin to the First World War , in which men lived in tunnels , redoubts , and sandbagged forts behind barbed wire defences . From 1951 until the end of the war , 3 RAR held trenches on the eastern side of the division 's positions in the hills northeast of the Imjin River . Across from them were heavily fortified Chinese positions . In March 1952 , Australia increased its ground commitment to two battalions , sending 1 RAR . This battalion remained in Korea for 12 months , before being replaced by 2 RAR in April 1953 . The Australians fought their last battle during 24 – 26 July 1953 , with 2 RAR holding off a concerted Chinese attack along the Samichon River and inflicting significant casualties for the loss of five killed and 24 wounded . Hostilities were suspended on 27 July 1953 . 17 @,@ 808 Australians served during the war , with 341 killed , 1 @,@ 216 wounded and 30 captured .   = = = Malayan Emergency , 1950 – 60 = = =   The Malayan Emergency was declared on 18 June 1948 , after three estate managers were murdered by members of the Malayan Communist Party ( MCP ) . Australian involvement began in June 1950 , when in response to a British request , six Lincolns from No. 1 Squadron and a flight of Dakotas from No. 38 Squadron arrived in Singapore to form part of the British Commonwealth Far East Air Force ( FEAF ) . The Dakotas were subsequently used on cargo runs , troop movement , as well as paratroop and leaflet drops , while the Lincoln bombers carried out bombing raids against the Communist Terrorist ( CT ) jungle bases . The RAAF were particularly successful , and in one such mission known as Operation Termite , five Lincoln bombers destroyed 181 communist camps , killed 13 communists and forced one into surrender , in a joint operation with the RAF and ground troops . The Lincolns were withdrawn in 1958 , and were replaced by Canberra bombers from No. 2 Squadron and CAC Sabres from No. 78 Wing . Based at RAAF Base Butterworth they also carried out a number ground attack missions against the guerrillas .   Australian ground forces were deployed to Malaya in October 1955 as part of the Far East Strategic Reserve . In January 1956 , the first Australian ground forces were deployed on Malaysian peninsula , consisting of the 2nd Battalion , Royal Australian Regiment ( 2 RAR ) . 2 RAR mainly participated in " mopping up " operations over the next 20 months , conducting extensive
