THE 1930’S
South’s had a more successful decade in the 1930’s winning 2 premierships in 1938 and 1939 with some excellent sides participating in the Great Northern Association. In 1938 R Curyer was the Association Champion winning the Mail Medal representing Souths. D Barry Snr. continued to volunteer as President in the early 1930’s with H Luke becoming President for 2 years in 1937 and 1938.  R Curyer was the champion player of this era winning 3 Best and Fairest awards.

In 1931 Wilmington joined the competition. South’s improved marginally this year but lost the semi final Centrals 8-12 (60) to 1-5 (11).  The year 1932 was poor for the club and once again they finished at the bottom of the ladder however in 1933 they improved greatly to finish second, unfortunately the lost the Grand Final to West 8-17 (65) to 4-8 (32). Football lapsed in 1935 due to a number of reasons and play was restricted to several inter-town matches. In 1937 South’s were expected to field its strongest team after many slow seasons. After picking up R Curyer from South Adelaide, the league selection policy dictated that South’s were able to obtain its players from Conway town and the extension of Flinders Terrace. Players who represent Port Augusta in 1937 from South include F Copley, B McGuffie, B Lehman and H Zanker. South’s had 130 members for the year. The ladies who ran the social committee were Mrs G Scrivener, Mrs H Corbett, Miss l McCartney and Mrs HTM Luke. Their efforts were hugely recognised as they organised regular dances every Thursday evening at the Parish hall. All matches were played at Central Oval and these ladies sold afternoon tea to raise money.

In 1938 South’s broke through for their first Premiership in 10 years when they defeated Centrals in one of the best matches witnessed in this town for many years. When the final bell rang South’s had the upper advantage of just 4 points! J Rodriquez coached them through the season undefeated and to this victory. Although South’s did not have the services of their regular full forward H Nicholson who had injured his fingers, both teams were at full strength. Fast and brilliant football especially in the last half was produced by both teams and the spectators were kept on their toes as each team attacked in turn.  Final Scores were South’s 8-6 (54) defeating Centrals 7-8 (50). In 1939 the shield went to South’s for the second year in succession.  Grand final scores were South’s 11-12 (78) to Centrals 5-12 (42) the team was ably coached by Lyle Reeves and best player in the Grand Final was W. Smith. Jack Shinnick was the President during this successful year and players who represented Port Augusta from South’s included H Nicholson, W Smith, R Flanagan, J Fullerton, H Burton, J Cosgrove, L Reeves and R Curyer. D Barry was awarded a well deserved Life Membership of Great Northern Football Association.
