In complete contrast to a year ago, England have arrived in Perth with the intent to sweat it out and become battle hardened in time for their three-match ODI and five-match T20 series against Australia.
It was a different case last year, when England played a low-key intra-squad hit-out on a lifeless Lilac Hill wicket in preparation for the first Ashes Test at Optus Stadium.
The result?
A Test match that lasted less than two days and set the tone for Australia's 4-1 series win.
This time, England will take on Western Australia in a white-ball match at the fast and bouncy WACA, before facing Australia in the ODI series opener at Optus Stadium on November 13.
The ultimate goal is to win the ODI World Cup in Africa next year, and Brook says having a hit-out at the WACA will leave his team well placed for their coming return to Optus Stadium.
"Yeah, the conditions (at the WACA) are obviously a lot closer to Optus than Lilac Hill is," Brook said on Friday.
"The bounce, the carry, the pace, the pitch - it's miles away from what Lilac Hill offered us.
"But thankfully, we've got the opportunity to play here (at the WACA) and train here over the last couple of days, and we're really looking forward to it."
Brook wants England to become the fittest and strongest team in world cricket.
Words are cheap, but England's actions since arriving in Perth show they are serious about getting fit.
"We've kind of used it as a little bit of a training camp," Brook said.
"We haven't really had that as a white-ball group over the last few years.
"The last few days has been really good. We've had some good chats, good training sessions.
"We went for a nice run as a group around Perth, and got to see a few of the sites."
Brendon McCullum was axed as Test coach earlier this year, with the poor Ashes build-up and heavy defeat to Australia playing a part in the decision.
But he remains coach of England's white ball sides, and has ordered them to become super fit and play dynamic cricket.
England's recent tri-series against Sri Lanka and Pakistan in Pakistan was underwhelming, with three losses and a win.
But the one bright spot was Brook posting the fastest double-century in ODI history, off just 114 deliveries.
England are intent to turn around their form against an Australian outfit that's rested pace stars Pat Cummins, Mitchell Starc and Josh Hazlewood.
"With the World Cup 12 months away, it's a good period now to try to nestle down and hone in on the skills and lessons that we've learnt," Brook said.
"The key thing is to try to be one of the fittest and strongest sides in the world to be able to try to dominate throughout that competition."
Australian rising star Mahli Beardman will feature for WA against England ahead of his ODI debut.
And Lance Morris, who has been sidelined for more than 18 months with a back injury, will also line up for the home side.
