The Black Ferns have played three tests since the new coaching group took over in April, sweeping the Pacific Four series with wins over Australia, Canada and the United States.
The group haven't had a lot of time to work but their impact on the team has been clear and the two-test series against Australia will be the Black Ferns' last playing opportunity before the World Cup starts in October.
"We've got a little mantra that we've been trying to bring to life. That's 'like never before'," Simon said.
"We've never had a World Cup in New Zealand, we've never had full-time contracts, so it's just fitting to be taking another step higher. Bring that high performance to life, showing New Zealand and the world that we're capable of more."
Simon will co-captain the Black Ferns tonight with first five-eighth Ruahei Demant, and was one of two returning players, with No 8 Charmaine McMenamin back in the side after dealing with a spinal injury.
Simon echoed Smith's sentiments that the two tests against Australia are a balance between trying to get a result and building towards the World Cup.
"These are obviously building blocks," Simon said. "You want to get better. We have to put it all out there; the product has to speak for itself."
