Finals
All four finalists had been decided before the end of the final round and by coincidence faced each other in the penultimate round. 1926 wooden spooners St. George had a massive turnaround in 1927, with a chance to become minor premiers in the final round when they played South Sydney who were just one point ahead of them on the ladder. However looking for their third successive title, South Sydney prevailed 22-9 in front of a large crowd of 26,649 at the Sydney Cricket Ground, and as a result took the minor premiership. On the same day, Western Suburbs and Eastern Suburbs played each other for third spot, with Western Suburbs winning 8-6.
In the semi-finals, both South Sydney and St. George overcame their opponents and were able to set up a rematch of their Round 18 game just two weeks earlier.
