That wasn't the case for the Blues in their loss to the Brumbies in a wet Canberra in April, but with players such as Woodcock, Patrick Tuipulotu and Jerome Kaino in their pack, the Blues should be confident of gaining the necessary edge in the collisions in Perth.
Of these three, Tuipulotu could be the most important.
The young lock's taste of test rugby against the English - he played four minutes in each of the tests in Dunedin and Hamilton after remaining on the reserves bench in Auckland - has left him hungry for more.
And the 21-year-old knows expectations have risen accordingly.
"I have to play at another level up now," he said. "In Super Rugby especially, more people will be watching me now so I have to perform. It's going to push me. I'm here now, it's mine to lose, so I've just got to perform."
The Blues could certainly do with a ruthless attitude, and with his size and skill, Tuipulotu has the ability and physical attributes to deliver it.
Their 37-24 victory over the Hurricanes at Eden Park before the international break was one of their best of the season and again highlighted the talent and potential in their ranks.
Transferring that to fields away from home is a puzzle they haven't been able to get to grips with, and at 10th on the leaderboard with only three matches to go, it seems too late for a charge to the playoffs.
Those matches - against the Force, the Crusaders in Christchurch and the Chiefs back at Eden Park - give the Blues a tough end to the competition, but it will be important for Kirwan to see a continuation of the form and desire his team showed against the Hurricanes.
After rubbing shoulders with All Blacks Sam Whitelock and Brodie Retallick, Tuipulotu knows the level he has to reach is a high one.
"You watch these guys play and it's unreal to see how good they are in person, to see how professional they are, especially Sam Whitelock.
"Being the main caller in the lineout, I try to take a few things off him in that area. Brodie Retallick in the breakdown area, he's just ruthless."
