No, it will never affect your AUS PR. If you are working in Canada then you have to tell that otherwise you can mention what you like.
If i would be you then i would have said "Claim PR" as this will give 2 advantagesThanks for the reply! I'm not working in Canada. I just went there to claim my PR and returned in a week's time. That's where I'm confused, whether to say that it's for PR claim or can just mention holiday & leisure. My one time entry VISA to Canada is there on passport. As you mentioned that Canada PR won't affect AUS PR decision, I think it's better to mention the travel is for PR
Choose what you like most, but Canadian PR is not going to have any kind of effect on your AUS PR as many Canadian people also migrate to AUS due to weather.If i would be you then i would have said "Claim PR" as this will give 2 advantages
1) You are good competitive candidate that's why got PR
2) Canadian gov has already scrutinized your documents which adds weight to your profile.
