FREMANTLE coach Mark Harvey has thrown the spotlight on the AFL's draw, describing it as the "most uneven" part of the competition ahead of a challenging three-week stretch for his 5-1 side.

The club has a six-day break from last Sunday's western derby until it faces the Brisbane Lions at the Gabba on Saturday night, then returns to host Collingwood on another short week before travelling to Sydney.

Harvey was quick to point out that the Lions have travelled the last two weeks - and all sides are coming of a fixture with a close rival - but he said the League's fixturing was falling short.

He said it should be mandatory for the travelling side to have at least a seven-day break.

"The most uneven part of the game is perhaps the draw," Harvey said from Fremantle Oval on Wednesday. "That’s how I see it.

"It's not until you've been over here for a period of time and you see what the club and the team goes through."

Harvey said Fremantle, which will have a light week on the track and fly to Brisbane on Thursday, would be doing everything it could to sustain its form over the testing three-week period.

"That's our only answer at the moment and whatever happens at the end of the year, let's hope that we can progress with the thought process on the draw," he said.

"It will test the resolve and the mental toughness of the group over the next three weeks and that's the way we're approaching it."

Fremantle has never won at the Gabba in eight attempts, but Harvey said his in-form side had every chance of notching an inaugural victory.

Key backmen Chris Tarrant and Luke McPharlin, who are forming one the competition's stingiest combinations in defence, could control the back half against Lions Jonathan Brown and Brendan Fevola.

"They've got a really good rapport [and] they've become a lot closer now that we're playing them down there together and not up either end," he said.

"I think there's more improvement in them.

"Stopping the supply would be the No.1 thing. Our ability to sustain pressure up the field stops the quality of supply, [so] you'd like to think that we can control that area of the ground, but it remains to be seen."

Chris Mayne (leg), Alex Silvagni (ankle) and McPharlin (ankle) were all cleared of injury on Tuesday, but Harvey said the trio faced fitness tests at Wednesday night's training session. He expected all to travel.

Nick Suban will also be closely watched at training with the emerging midfielder ready to return after missing three weeks with an ankle injury. Harvey said the 19-year-old would not necessarily have to return through the WAFL.

"He never missed a game last year and he's an important fabric of the team," Harvey said.

"He'll train tonight [and] it'll be the first real opportunity he's had to join in. It's just whether we think he's ready to go for this particular game."

Harvey said Byron Schammer was a big chance to play his first game for the season after a stretch of WAFL form that has seen him average 26 possessions for Claremont.

His 27-possession performance on the weekend was considered to be his best for three weeks.

"Guys have to play three or four really good games at WAFL level to get a chance," Harvey said. "He's a big chance this week."
