The competition's top four, Warilla-Lake South, Shellharbour City, Gerringong and Nowra-Bomaderry, all came away with wins, while it appears Jamberoo, Kiama and Berry will fight it out for the fifth and final spot for the post-season.

At Michael Cronin Oval, Gerringong avenged their upset loss to Kiama earlier in the year, downing the Knights 34-6.

After a scrappy start to the match Gerringong built an 18-0 lead on the back of some strong defence and strong showings from their big names.

The Lions went back-to-back when they opened the scoring, Patrick Cronin crashed over and Nathan Ford did the same in the next Lions attack.

Brad Davidson then sent Lloyd Bowen over and Joel Roberts' three conversions rounded out the scoring for the half.

The Lions added another try straight after play resumed through Joel Doosey, before Kiama hit back through Cameron Whittaker.

Gerringong then put Kiama to the sword with converted tries to Rixon Russell and Adam Moore.

At Kevin Walsh Oval, Jamberoo kept their finals hopes alive with a 44-24 win over Albion Park-Oak Flats.

In the opening stages, Superoos raced out to an 18-0 lead in as many minutes thanks to converted tries to Ben Barnard, Josh Saunders and Simon Maslanka.

The lead was cut to six soon after though, the Eagles grabbing converted tries through Matt Carroll and Dean Gray before a four-pointer to Saunders gave the home side a 22-12 lead at the break.

Jamberoo blew their opponents off the park in the second half, quick-fire tries to Barnard, Mark Asquith and double to Matt Coehlo blew the score out to 44-12, before Carroll and Sean Jenkins scored consolation tries for the Eagles.

At Ron Costello Oval, Shellharbour piled on the misery for Berry with a 46-6 win.

The Sharks led 14-0 at half-time thanks to Jamie Manukonga's early try and then Ian Catania's double, before running away with it in the second half.

Ryan Schuster, Kurt Field and Goodwin ran in tries in quick succession to make it 30-0.

Manukonga then grabbed his double before Hans Schuster went over and Field's second made it 46-0.

Berry's Andrew Wright grabbed a consolation try on the full-time siren for 46-6.

At Bill Andriske Oval, Warilla-Lake South took another step towards the minor premiership with a 40-10 win over Milton-Ulladulla.

Three tries to Blake Colgan and one to Keiran Rankmore saw Warilla take a 20-4 lead at the break, Milton's lone four-pointer coming through James Patterson.

Colgan grabbed his fourth try after the break and the Gorillas added another three tries through Joel Skeates, Chad Lisch and Luke Roberts.

Patterson grabbed his double for the Dogs to round out the score.

At Nowra-Showground, Nowra-Bomaderry accounted for Port Kembla 40-22.
