Eastern Suburbs 37-24 Northern Suburbs

Eastern Suburbs scored three unanswered tries in the final 25 minutes to claim a statement win over last year’s grand finalists and hand Norths their second successive loss.

The two sides traded tries in the opening 30 minutes, with Easts leading Norths 15-14 after outscoring the visitors three tries to two.

Both sides added penalty goals late in the first half, giving Easts an 18-17 lead at the break.

Norths took the lead early in the second half when Gary Bautz found the line on the back of a dominant five metre scrum but it was all one way traffic in the final half an hour.
