The 25-year-old is set to start the three-day game against Sussex which begins on Friday as one of a number of players looking to force his way into Darren Lehmann's Test team.
Australia's batting line-up has flagged badly across the first two Tests and a good performance against Sussex could see a fringe player such as Wade propelled into the next Test at Old Trafford.
Wade is on the tour as an understudy to keeper Brad Haddin, but would be happy to play as a batsman only if needed.
"It's a huge opportunity for everyone who's not had a game," he said.
"The Ashes tour has not started like we wanted, but to get an opportunity to play, which I've not had for a couple of months, is great for me.
"I am here as a back-up wicketkeeper but I want to get amongst the runs and push for a spot as a batsman. I'd take a spot where I can get one, wicketkeeper or batsman.
"If I get a tap on the shoulder to play a game, especially an Ashes game, I'll take it."
