following day (episode 1,113), an event that marked the final scenes of the entire series. He never marries again after the death of Grace. John (John David Sullivan) – born 12 October 1919 (Andrew McFarlane) was Dave and Grace's eldest child. A medical student at Melbourne University in 1939, he was vehemently opposed to the war, leading to many confrontations with his more traditionalist father. John's relationship with German-born Anna Kaufman (Ingrid Mason) also caused complications. Anna died on 20 December 1940 (episode 117). After her death, John relented and joined the medical corps, leaving the family on 4 June 1941 (episode 228). He was lost at sea and, for two years, presumed dead. His return to the series prompted Grace Sullivan to fly to England where John was convalescing. John was featured in "The John Sullivan Story" (see below) and intermittently in the series again between episodes 505 and 616. Tom (Thomas William Sullivan) – born 12 June 1921 (Steven Tandy) was the second Sullivan child, an engineering student who, unlike his brother John, was keen to sign up and fight for his country. Tom served the duration of the series in the military, serving in North Africa, Greece, Crete, the Netherlands and Malaya and eventually reaching officer rank. Late in the series he returned to civilian life, took up university studies and married an American lawyer, Patti Spencer (Penny Downie) on 4 September 1946 (episode 922), though it was not a successful marriage. Terry (Terence Charles Sullivan) – born 7 April 1924 (Richard Morgan) was the third and youngest Sullivan son. A scampish schoolboy at the beginning of the series, as he matured he harboured dreams of joining the Air Force, but an inner ear problem prevented this (episode 294) and he joined the army instead (episode 301). He later married Caroline O'Brien (Toni Vernon episodes 273 to 493; Geneviève Picot episodes 666 to 888) on 22 September 1942 (episode 334); however, the war took a greater psychological toll on Terry than his brothers; he was interned in Changi Prison and he struggled both with his marriage and his readjustment to civilian life. Terry was jailed on 9 May 1946 for 10 years for stealing explosives and assault (episode 886). He escaped from jail with Victor Fisher, another inmate, on 18 August 1948 (episode 1,111). He was indirectly responsible for the death of his father Dave in the
