Tech Tahs coach Tim Olsen has challenged his side to show they can mix it with Illawarra Rugby's top teams throughout the final two weeks of the season.
With no finals this year, the premiership will likely be determined when Avondale takes on Campbelltown on Saturday.
The Wombats can secure the title with a win over the Harlequins, while the hosts require a victory to keep their slim hopes alive.
Despite sitting sixth on the ladder, Olsen said the Tahs still have plenty to play for.
With matches against Shoalhaven and Vikings to close out the competition, the coach is eager to see his side prevail over perennial finals contenders.
"Saturday is another challenge," Olsen said. "Playing a team higher above us on the table, we need to beat Shoalhaven if we want to be in the top four.
"If we were playing for finals positions, we need to win these games so we can prove to ourselves that we are worthy."
Tech and Shoalhaven played out an entertaining game in round three, with the Shoalies kicking a match-winning penalty goal at the death to prevail 29-28.
Olsen is anticipating another high-scoring affair and said the Tahs must shut down the Brandon brothers if they are to reverse the earlier result.
"They knocked over Shamrocks with a big score, so we know what we're up against. They have quick outside backs, we can't give them any room to move."
The final two games of the round will see Shamrocks host Kiama and Vikings play Camden.
