played in the Southern Districts Rugby League. Bowral, Mittagong, Moss Vale and Thirlmere were regulars in the Berrima premiership. From 1924 to 1930, a knockout competition, the Warleigh Cup, was held at the end of the season in senior, reserve and junior grades. Between 1928 and 1930 the Warleigh Cup was played in lieu of premiership finals. In 1931 the cup was held in May. At the northern end of the region Camden, Campbelltown, Picton left the SDRL and with Bargo and Thirlmere formed the Wollondilly association. Senior and junior competitions were held in 1929. In the early 1930s, premiership football gave way to a plethora of challenge cups, which had begun to be introduced. The high rate of unemployment was cited as a reason for favouring challenge cups over competition. Typically, a cup was donated to a club and matches were arranged to contest its possession. A cup might change hands multiple times during a season. The club that originally owned a cup often had the right to challenge the holders in the last match of the season in which the cup was on the line. Names of the cups included Sommers, Citizens, Cornwall, Commercial, Dawson-Lack, Dawson-Frazer, Theo Small and Murphy. There were cups for reserve grade – Burchell, Dresher and Whyte – and junior teams – Wales & Jackson. Competition in a round-robin format resumed in 1935, with Group 6 clubs organised in northern and southern divisions and a handicap system applied. Group 6 disbanded in 1936 and no competition was held. Berrima District Rugby League reformed and conducted competitions in 1937. Bowral won the final 23 to nil but lost the title on a protest by Mittagong, upheld by the league. A resident of New Berrima had played throughout the season despite not being residentially qualified to play with Bowral. Despite a warning from Mittagong, he played in the final. Berrima mixed a four-team competition with challenge cup matches in 1938. Meanwhile, the re-formed Wollondilly District experimented with a one-day carnival premiership. A re-established Group 6 coordinated a cup draw in 1939. Despite the war, some senior football was played the following season. Burrawang-Robertson and two Bargo teams participated in a 1944 competition with premiers Bowral and runners-up Mittagong. Campbelltown, Moss Vale, Picton and Thirlmere resumed playing the next year. Group 6 Era 1946–68: Highland Fling 'Group 6', as it is now known, officially recommenced in 1946
