The Football Ferns have high expectations and want to build on their good performances at the 2011 World Cup in Germany. They are in a tough group with Great Britain, Brazil and Cameroon but Wilkinson said there were no easy opponents in the 12-team competition.
"At least we're not in the same group as the US or [World Cup champions] Japan. I think the most challenging game for us will be against Brazil but they'll all be hard games no matter which pool you're in," Wilkinson said.
The team will play Great Britain with the world watching. Their match at Millennium Stadium in Cardiff is the first act of the Games and precedes the opening ceremony by two days.
"I'm not too sure what will happen but starting in the first game in particular is what I'm aiming for and of course if I get on the pitch I want to get some goals - that would be amazing."
The quad strain she nursed through the selection campaign has healed. "I'm all good now and I've had no trouble with it in my recent games so if I keep looking after it, I'm not expecting any more problems."
Wilkinson said the collective experience of the side meant they would not be overawed by the event. "We've already proved that we can match it with some of the world's best teams and we now want to go one step further and show we can defend a lead and win games and maybe progress through to the next round," she said.
Women's football started at the Atlanta Olympic Games in 1996, with eight teams competing. This tournament features 12 teams and the Ferns want to improve on their debut, at Beijing four years ago, where they drew one game.
Proud parents Simon and Karen and her brothers Tom and Samuel will all attend her Games in Britain. Yesterday was a rare chance to get some family time, with the young striker set to continue her busy football schedule after the Olympics.
"I have the U20 World Cup in Japan straight after the Olympics and when that's finished I leave for the States," she said.
She has won a football scholarship to the University of Tennessee where she will study psychology but that won't stop her taking part in international football.
"That's the advantage of going to Tennessee and that's why I chose to go there, they're really flexible about their players' international commitments and I want to keep playing for New Zealand as much as I can," she said. "I won't be the only player based in the States so I'm hoping this won't be my last Olympic Games.".
TheFerns have warm-up games in Switzerland against Canada and Colombia scheduled before their first match against Britain on July 25.
