SYDNEY- Wallabies prop Sekope Kepu says high-stakes derbies like tomorrow night's showdown between his NSW Waratahs and the Brumbies is why he plays rugby.
Kepu likens the Super Rugby blockbuster at ANZ Stadium to State of Origin rugby league where, as they say in the promos, it's state against state and mate against mate.
"There's nothing better," Kepu told AAP.
"You're playing your mates but you put that aside and go out there and play against each other.
"You can only get better."
Fresh from helping the Wallabies to a 3-0 series sweep over France, Kepu said locking horns with old interstate adversary and long-time Test teammate Ben Alexander who's returning for the Brumbies from a neck injury only adds to the occasion.
"They've got quality front-rowers there in Scotty (Sio) and Benny and they'll definitely test us," he said.
"Last time we were down there we didn't do too well so we're looking to improving on that performance."
The second-placed Waratahs can all but secure Australian conference honours with victory over last year's Super Rugby runners-up, who must win to retain control of their finals destiny.
