Looking For Points Help - YYZ to SYD
 

A couple of years ago I got an RBC Infinite Avion VISA so we could start saving points for a business class flight for our vacation to Australia planned for Feb 2015. I've collected 200k points so I thought I'd check point requirements for later this year (as a test) and found that I have enough for 2 economy seats but, using Infinite Avion points. I can only upgrade to business class by paying the difference in cash which works out to over $4,000 per person.

Can anyone suggest to me either a better use of these points (conversion to another program that will get me to Australia without multiple layovers and in a reasonable time frame in business class)? Either that or a better program where I could collect points that can be redeemed for business class flights. Our normal spending patterns put about $75k / year on a card.
