Has anyone had any luck booking Brisbane to Vancouver business on Air Canada with Velocity points?

Hi all, as above. I have been unable to find a single business reward flight between BNE and YVR. Does anyone know if these are made available by Velocity at any point in time and what time of day the reward flights are typically added to the Virgin website?

I believe I have seen them before on the website. Not with any regularity though. They are probably not the control of Velocity but rather Air Canada deciding to release seats and they aren’t exactly the most generous even to their own members in that regard.
