Neep advise about visa

I want my Canadian fiance to visit me in Australia on a 12 month tourist visa. We are not yet financially ready to do the prospective fiance visa. I have heard that if they see a hint of a relationship on a tourist visa it will be automatically rejected, i did however find this ionfo on a Ukraine site for Russian women getting visa's so I dont know if that rule applies to Canada. Would he be more likely to be approved for a 12 month tourist visa if he states on his app that he is coming to visit friends or will it be fine to put that he want the visa to come visit his fiance? Any help would be so apprecieated, I don't know what to do about tis.
