Bomaderry is on the verge of securing the 2021 competition championship after grinding out a tough 3-1 win against Manyana on Saturday.
At Bomaderry Oval, goals from Jordan Haddow, Brock Toscan and Benjamin Seyffer secured the hosts all three points, despite a strike from Wanderers' Mathew Pepper.
This win, the Tigers' 10th of the Shoalhaven District Football Association, moved them onto 35 points after 16 rounds, while the Wanderers' finals chances are all but over - as they sit on 22.
Hot on the heels of the league leaders is Huskisson-Vincentia, who leapfrogged Shoalhaven United into second thanks to the bye.
The Seagulls are in second on 32 points, closely followed by United (30), who lost 2-nil to Milton-Ulladulla at Lighthouse Oval.
Two goals from Ivan Katusa, one in the 18th minute before a 90th-minute penalty, secured the hosts maximum points and kept them in contention for the top-four.
On the flip side, United, who were forced to play the final 21 minutes of the match with 10 men after Connor Hughes was shown a second yellow card, have are winless from their past four matches.
On 29 points, one ahead of Milton is Shoalhaven Heads-Berry, who drew 2-all with St Georges Basin at Vic Zealand Oval.
The Dragons raced to a 2-nil lead between efforts from Rory Meyer (11th minute) and Dane McGinn (27th) before the Sharks clicked into the gear.
Nathan Thomas pulled one back for the hosts in the 38th minute before equalising in the final minute, to secure his side a vital draw.
Evan Leedham found the back of the net for hosts at Sharman Park while Rhydian Taylor netted for the Brumbies.
All these results see five teams remain in the hunt for semi-final spots, with Basin (22), Manyana (22), Illaroo (17) and Callala (12) all out of contention.
Looking ahead to the penultimate round 17, Huskisson host Bomaderry, United play Illaroo, Manyana battle Basin and Heads takes on Milton, with Callala having the week off.
