Leaders Kiama avenged their only loss of the season to Northern Districts with a thrilling nine-point victory at Hollymount Park on Saturday.
Kiama trailed by eight points at half-time and two points at three-quarter-time but came home the stronger in a tight 12.11 (83) to 11.7 (74) contest.
Norths beat the Power by four points in the opening round but Kiama have now won eight straight to consolidate top spot.
Ben Williams and Ricky Neels each booted three goals for the Power in one of the best South Coast games of the season.
Meanwhile, Bomaderry Tigers reaffirmed their hold on equal third with a dominant second half in a 48-point victory over Nowra at Artie Smith Oval.
Nowra were coming off a morale-boosting win over Port Kembla and led the Tigers at quarter-time before the home side asserted their class in a 13.17 (95) to 6.11 (47) victory.
Bomaderry booted eight goals to one in the second half and are positioned equal third with Northern Districts, just one win behind Wollongong and two wins behind leaders Kiama.
All teams were coming off a general bye for the June holiday weekend, but Bomaderry were desperate to bounce back from a tough loss to the Power in round nine.
Brayton Varco booked three goals for the Tigers, with Jack Hangan and Brent Herdman managed two goals each.
Tristan Balazic snared two goals for Nowra and with Cabbot Stewart-Browne was outstanding for the visitors.
In the other round 10 matches, premiers Wollongong were made to battle for a tough 15.13 (103) to 14.7 (91) win over a spirited Shellharbour at Keira Oval while Figtree had to settle for a forfeit win over last-placed Albatross, who embarrassingly were unable to field a team for a third time this season. Port Kembla had the round 10 bye.
