This was the first time the championship was held outside the United Kingdom. It would be hosted in Australia again in 1975. The initial stage was a round robin in which each competitor played a 3-day, 37-frame match against four of the other eight competitors. It is the only time a round robin format has been used in the world championship. The first match between Paddy Morgan and Warren Simpson was from 28 to 30 September and was won by Morgan by a score of 21–16. Eddie Charlton and Norman Squire met in the second match, during which Charlton made a break of 106, the first century of the championship. The British players did not start their matches until 6 October when John Spencer, John Pulman and Gary Owen started their first matches. Ray Reardon started his first match on 9 October, beating Perrie Mans. Spencer made a break of 105 in his second win, over Norman Squire. Reardon and Spencer played again from 12 to 14 October. Reardon beat Charlton while Spencer beat Pulman. Charlton made a break of 116 while Pulman made one of 113 while Spencer a 102 break. Simpson met Owen from 13 to 15 October. Owen led 17–14 and 18–17 but Simpson won the last two frames to win 18–17. Owen scored his first century in his match against Squire, a break of 102. Owen and Charlton won their second matches and met over the following three daysl. Reardon met Morgan in Brisbane and led 20–10 after the final afternoon session. The third win guaranteed his place in the semi-final where he would meet John Spencer. Charlton beat Owen to give him his third win and a place in the semi-final. Charlton made breaks of 129 and 124 on the final day. Simpson then beat Perrie Mans 19–18 to gain the last semi-final place.

The basis on which the semi-final draw was organised is not known. The 22 October edition of The Sydney Morning Herald reports that Reardon would play Spencer in the second semi-final. At the time Reardon and Spencer still had to play each other and Charlton, Owen and Simpson also had one match to play. So the final order of the group was still undecided.
