The Dockers, with only one win this season, host the reigning premier in a match Harvey has primed his side for - hoping the efforts seen in a strong second half against Adelaide continue.
"We haven't played too badly other than in one game and there's a genuine perception in the public that perhaps this is a game Fremantle might win, but what we can't do is go out there and play in awe of Geelong," Harvey said. "They are coming over to play on our soil and we have to make them feel uncomfortable about that.
"There'll be a bit of unpredictability in the game, but Geelong just plays their way, so you can only make a subtle change. The challenge is to beat a team that nobody thinks can be beaten at this stage."
Even though forward Chris Mayne will miss again through injury, Harvey continues to back his young players.
Rhys Palmer, Garrick Ibbotson, Marcus Drum and Clayton Hinkley - all good against Adelaide - can expect to hold their spots, with midfielder Brock O'Brien a chance to play after terrific WAFL form for Peel Thunder.
With three key forwards pressing to play, Chris Tarrant appears likely to remain with East Perth as he regains full fitness. Ryan Murphy kicked six goals for South Fremantle and Adam Campbell had five for West Perth, but it was Kepler Bradley that was most impressive with 23 possessions, 10 marks and four goals.
"There has been a reluctance to play younger guys over the last couple of years," Harvey said. "They might make a crucial error at the wrong time, but they do add enthusiasm, excitement and sometimes a team needs that.
"Mayne won't get up again, which is unfortunate, but we will sit back and watch the continued development of Palmer, Ibbotson, Hinkley, Drum and Warnock isn’t too far away. O'Brien isn’t far away, all our talls played well at WAFL level and we will make one or two changes.
"It's fair to say that Chris has an injury, we don’t need to discuss what it is, and it will take him a while to overcome. He'll be able to play, but is restricted. At this time, it's best for him to play a full game, but I'm not pre-empting him not being in the side."
Harvey knows all about Anzac Day encounters and will make his players aware of its importance while retaining a focus on the game.
"You make players understand the relevance of the day and how Australians would want them to play the sport and represent what has been done in the war," he said. "However, you get that across to the players and then get the best out of them from a playing aspect is intrinsic.
"When the bugle plays, nothing beats it. That really gets the adrenaline going and then you have to go out and perform. The build-up to the games is significant and is very much a big part of the remembrance."
Harvey is looking forward to taking on his premiership teammate Mark Thompson in the coaches' box for the second time, gently reminding him about the cover he used to give him in their playing days.
"I used to have to play on two players, one of which was his opponent," he said. "We always had that understanding between each other of reading the game and that holds you in good stead as a coach.
"We always have been because we went to school together and the friendship has spanned 25 years. He knows I won't call him this week, but I will see him after the game and hopefully we have something to talk about."
