GWS enter the final round sitting fifth, well ahead on percentage of West Coast and the Western Bulldogs.
A first win over North Melbourne should secure them fifth at worst and perhaps even a top-four spot.
Cameron said he viewed Saturday's game at Etihad Stadium as a final for his side.
"We'll finish full steam ahead so there will be no holding back from our end," Cameron said.
"They are starting to get some players back and I'm pretty sure they will attack it 100 per cent as well.
"I think they will be fully wound up. They might have some players coming back that are clearly in their best 18, so they will want to make sure that they get a really good hitout.
"There's so many things that probably can stem from this match in terms of ladder position, but we can't control what happens with the other teams, so we've got to go 100 per cent on Saturday night."
He doubted the two sides would keep anything back from each other despite a strong chance they would clash again in September.
"There could be some with run-with roles on the weekend that they might do and we might do but I don't think that will change two weeks on if we happen to confront each other," Cameron said.
He regarded the last-round showdown against a potential finals adversary as a good lead-in to their inaugural September campaign.
"You want to come in (to finals) match hardened and match fit and playing against some really top opposition and we're going to get that on Saturday night," he said.
With the top-four sides level on points and fifth, sixth and seventh all one win back, Cameron anticipated none of the finals-bound teams would be coasting.
"The shifting of spots on the ladder just makes it full-on footy," he said.
