"They will change things, they will try things, you will be given an opportunity," Vickery told BBC Sport.
"The days of guys sitting on the bench for years on end, not getting on the field, are gone. It's an opportunity for me this weekend - I'm going to try to put pressure on, because Matt will be back.
"It's about us creating an atmosphere, and workman-like relationships, to push each other, and ultimately for the benefit of the England team.
"I want to play for England and be involved with this team. When I stand on the field and sing the national anthem, I mean it."
As well as the 2003 World Cup final, Vickery can also fondly recall his part in victories over the Wallabies at Twickenham in November 2005 and last year's World Cup quarter-final in Marseille.
But the Wasps veteran, set to win his 66th cap, has warned that Australia will be no pushover this Saturday.
Vickery eager to grasp opportunity
"It doesn't matter if you've got one cap or 50 caps, you know you're going to have to raise your game a considerable amount to compete with these guys," he added.
"I've been fortunate enough to play Australia a few times and there is no bigger Test match.
"When you look at the Australian team and how they've progressed, particularly in the forwards, since 2007, they've had a dramatic improvement.
"As always they don't go away and moan, they go away and improve, analyse what they need to, and of all the teams they've impressed me most.
"What happened in Marseille happened back then. Memories are great things but ultimately it's about this weekend and I've been around long enough to know the difference between success and failure, at international level, is the small details."
