Shellharbour will start major underdogs but won't be overawed by South Coast powerhouse Kiama in Saturday's clash at Myimbarr Oval.
Shellharbour overran Nowra and Port Kembla in the past fortnight to post consecutive victories in first grade for the first time.
Co-leaders Kiama will be a much tougher opposition, however Shellharbour - along with Figtree - have been big improvers this season.
Kiama lost by less than a goal to Northern Districts in round one then won four straight before they had last weekend off with the bye.
In Saturday's other round-seven matches, Northern Districts back up from an impressive 80-point victory over Figtree to host Bomaderry at Hollymount Park.
Bomaderry were beaten by Wollongong last Saturday and won't want to make it back-to-back losses against another of the finals contenders.
Norths full forward Adam Carmody booted 10 goals against Figtree and will be a handful for the Tigers defence.
Wollongong bounced back to form against the Tigers and host Nowra at Keira Oval.
Nowra are coming off their first win of the season by thrashing Albatross.
In the other game, Albatross host Port Kembla, while Figtree have the bye.
Meanwhile, the Illawarra Lions face an early 10am start away to UTS Bats on Saturday in their round seven Sydney AFL clash at Waverley Oval.
The Lions (2-4) have lost their last three matches to slip to seventh but tried hard in a 10-goal defeat to leaders Balmain last Sunday.
Illawarra are battling a mounting injury toll and struggling for firepower, having kicked just 21 goals in their past four games.
UTS Bats (4-2) are in fourth spot with the Lions and will be desperate for a victory to stay in touch with the top five.
Ladder: Bomaderry 8, Kiama 8, Wollongong 8; Figtree 6, Northern Districts 6; Port Kembla 4, Shellharbour City 4; Nowra 2; Albatross 0
