I think that Manawaroa is the only chance that the Aussies have at 185, but I would still put the money on Taleb. The one worry with Taleb is he has not fought professionally for almost a year and a half from what I can find online. Age goes against Taleb and experience from number of fights is a draw, but I'd say that Taleb has faced higher competition. Could be wrong, I only know the Aussies from searching online.
I don't mind the politeness because it seems that the fighters are really bringing what they have and leaving it in the cage. If anything I think the CDN fighters were playing up that conditioning guy helping out the Aussies, but I'm equally guessing the production staff tried to get that going to get the drama higher.
