Figtree Kangaroos beat premiers Wollongong for the first time in first grade with a gutsy effort at Keira Oval on Saturday.

The Kangaroos trailed by a goal at three-quarter-time but booted four goals to one in the final term to post a deserved 10.6 (66) to 7.12 (54) victory.

James Quinn and Fred David were a real force for Figtree, booting four goals apiece.

Figtree coach Ash Cairnduff was elated with the four-quarter effort from his side.

"It was a real good contested game of footy and for us to beat Wollongong for the first time is a terrific effort," Cairnduff said.

"I knew we had a performance like this in us, we just had to back ourselves and go out there and do it.

"We tackled our hearts out, won the ball and used it well enough to beat a real good side like Uni."

Figtree have won three of their first five matches, and would have beaten Port Kembla in round four but for having an extra player on the field for a short time in the fourth quarter.

The indiscretion led to the Kangaroos having their entire score which represented a 70-point lead erased in a 26-point defeat.

Wollongong suffered a blow pre-match with their coach Lee Murray treated in hospital for concussion after copping a heavy knock late in the reserve grade game.

But Figtree's pressure and commitment were too much for the Bulldogs, who suffered their first defeat of the season.

In other games, Shellharbour celebrated their first victory for 2014, with an impressive 13.4 (82) to 5.8 (38) effort over Nowra at North Dalton Park.

Bomaderry consolidated top spot with a 22.18 (150) to 5.1 (25) thumping of Albatross at Tom Smith Oval.

Albatross kicked the first three goals before Bomaderry clicked through the gears with Jack Hangan best-on-ground, and Brad Graham booting six goals and James Lees five goals.

Kiama are in ominous form after a 23-14 (152) to 7.4 (46) home victory over Port Kembla.

Travis Lothian booted five goals and Ricky Neels four goals for the impressive Power.
