The "priceless" brilliance of Australian Women's Sevens superstar Ellia Green is not lost on Tim Walsh.
Green lifted the roof off Robina Stadium when Australia's clash against England was delicately poised, scoring a scintillating try which will feature on highlight reels around the world in the next 24 hours.
It was the kind of try that only Green is capable of - utilising the full range of her sublime attacking arsenal to burn two English defenders and burst right through another en route to the line.
It's the potent combination of speed and strength which makes her arguably the best finisher in world rugby.
"Speed is really, really important - it's priceless, to a certain extent," Walsh said.
"With Ellia as well, if she's not going to go around you, she will come through you.
"She's quite a talent from that point of view but in enabling Ellia to do that, you have to create the space for her.
"You have Charlotte (Caslick), Emma Tonegato and (Emilee) Cherry, the power runners in Sharni (Williams) and Shanno (Parry) and then Vani Pelite seems to do everything.
"But it's pretty handy when you can give Ellia some space - just a little bit - and you know that she will make the most of it."
Green was the star of the opening day of action on the Gold Coast but it was a team effort which dragged the Australians over the line against England.
Leading 17-12 early in the second half, England applied serious heat on the Australian line with a multi phase surge up the middle of the ground.
But some desperate tackles kept England out of the red zone and one minute later, Emma Tonegato was putting Vani Pelite away for what would be the match winner.
It was that resolve which pleased Walsh as he reflected on his side's showing post match.
"It doesn't sound like a long time but 14 minutes is a long time," Walsh said.
"If you can hold your composure and hold onto the ball, the defence will actually break down.
"I believe we've got the players to be able to expose that and we have the fitness to do it.
"I was worried but I knew if we tidied up a little bit the floodgates would open and we would come away with the win."
The sold out crowd added another element to which the Australians are now accustomed, as the cheer that went up as Green was deafening.
"We weren't thinking about it at the time but now we've had 10 minutes to think about it and it's been mentioned a couple of times, it really was something pretty special to hear that crowd and to watch the girls play rugby," Walsh said.
"It gives us a lot of experience and that's the beauty of a three day tournament."
There are some injury concerns for Walsh to contend with, though, as both Sharni Williams and Shannon Parry picked up knocks in the win over England.
The extent of those injuries are not yet known but it appears Williams, in particular, will be in some doubt to line up tomorrow.
