Looks like Iron Claw needs a good bigun clawing!
I'd have a look at
US&CA Home bongsolo for they have been known to offer best fares from Europe to Australia, so reckon they might have something competitive from Vancouver.
If you're talking of doing it around Xmas, you'll likely find pricing to be at a peak.
Could be a lot cheaper and even bigger surprise if you booked your friend a trip over to Canada if about then for have seen some super specials in past years for Canada return at about A$899 return plus taxes, usually with a limited stay duration of a month and marketed by
www.bestflights.com.au and would also not hurt to see whether they have something suitable for you or the friend.
