West Coast face an unusual test against Port Adelaide on Sunday, with the 12pm bounce (local time) at Adelaide Oval meaning the Eagles' body clocks will effectively be set to 9:30am (Western Australia is 2.5 hours behind South Australia).
It will be the earliest start to a game, in local time zone terms, a Western Australia team has ever faced.
Eagles coach Andrew McQualter says it's a common task the club deals with in having to often cross state lines to play football.
"It is what it is, and we're probably fortunate because we play two or three of our pre-season games at that time anyway," McQualter said on Thursday.
"Our guys are pretty accustomed to getting up early and performing, so we'll go over tomorrow and have a couple of days to get our body clocks sorted.
"We've been doing that already this week, and it's part of the preparation of AFL footy.
"Ultimately our job is to turn up and perform."
McQualter offered some insight into how the high-performance team and staff at West Coast have been helping the players adjust to the new body clock ahead of Sunday's clash.
"It's really simple things. Like all week we've been trying to go to bed 15 minutes earlier and wake up 15 minutes earlier," McQualter said.
"It's just normal stuff that West Coast has had to deal with its whole existence, travelling across time zones. There's a bit of science behind it, and our guys have done a great job of preparing our players."
From a selection standpoint, the Eagles have two forced changes due to the injuries of Harry Edwards and Milan Murdock.
Sandy Brock is pushing to be recalled in defence, which could help fill the void left by Edwards while Malakai Champion and Harry Schoenberg are vying for Murdock's position following his hamstring injury.
"He (Murdock) hasn't had a hamstring injury before, so this is new for him, but he's an optimistic person and he'll be attacking his rehab the way he attacks his football and hopefully it's not too long on the sidelines," McQualter said.
"The role of our small forwards is to pressure and create scoring opportunities, and he was providing both of those capabilities.
"He (Champion) has been building his form the last few weeks, and he's been quite impressive in the WAFL, so he's certainly coming into calculations."
