Corrimal moved to outright second on the IPL standings, while northern neighbours Woonona enhanced their finals hopes with vital wins on Sunday.
On their 130th anniversary weekend, the Sharks outclassed Fernhill 3-1 despite a determined second-half push from the Foxes.
Woonona were three goals up at half-time after two quick goals before the break, but Jack Lombo headed home off a well-worked corner to offer Fernhill hope.
However, Woonona kept their two goal advantage to ensure they are fifth on the ladder on 20 points, three behind second-placed Corrimal and six adrift of leaders Olympic. Rangers continued their remarkable rise, beating champions Bulli 2-nil, despite Lukas Stergiou being sent off with half-an-hour remaining after tempers frayed between the two teams.
Tomiki Wada's free kick handed Corrimal the lead in the moments before half-time, before Van Elia finished it off in the 85th minute.
South Coast United kept their top-flight torch burning, beating Tarrawanna 3-2.
