Reigning premiers Burnside remain unbeaten in the 2024 men's Premier Grade season following a 34-0 rout of Old Collegians.
The Double Blues were at their clinical best on the road against Old Colls, who failed to handle an early Burnside onslaught at Tregenza Oval.
Ben Moffat crossed inside the opening 90 seconds and Max Hodell's try in the 10th minute saw the visitors rolling at a point-a-minute early doors.
Further tries to Tony Barker and Hasler Monda saw Burnside hit the sheds 22-0 ahead and the game was all but over when Hodell bagged his second shortly after half time.
A late yellow card to Maxwell Monfries rubbed salt into Old Colls' wound as Tofu Sooaemalelagi scored Burnside's sixth to ice their win.
Meanwhile Joseph Parson's try in the dying minutes saw Adelaide University steal a 34-32 win from Woodville at Waite Oval.
The Wasps outscored their hosts six tries to four but Parsons' late score handed James Agness a chance to win it late and the Uni fullback obliged with his sixth successful kick of the afternoon.
Brighton and Barossa also enjoyed bonus point wins against Onkaparinga and Port Adelaide respectively while Souths took a full five points from Round 8.
Meanwhile Woodville remain the team to beat in this year's women's competition after extending their unbeaten streak to seven games.
Naomi Caucau's three-try haul anchored a 60-5 win over Uni with Brooke McHugh (two tries) and Victoria Cousins (13 points) among the Wasps' many stars.
Port Collegians returned to winning ways with a 39-5 victory over Barossa but the game of the round undoubtedly went to Souths and Burnside, who played out an 80-point thriller at AA Bailey Reserve with Souths emerging 41-39 winners.
The two sides scored eight tries apiece with Emma Yates' boot (two tries, three conversions) proving the difference for Souths.
In other competitions, Brighton kicked two wins clear atop the Reserve Grade ladder after Burnside pipped Old Colls 24-22 while the Double Blues also enjoyed success in Third Grade with a 31-12 win completing a Burnside away sweep at Tregenza Oval.
