How to get from east coast Australia to London with Velocity points?

Is it possible to get a return business reward seat ( happy with points and pay) using Velocity points BNE/SYD or MEL to LHR and return from Rome.I would also need to buy a seat as well for my husband.Travelling late August next year and returning early Oct I’m thinking by the time I can book the return seat the departing seats would all be gone. New to this and appreciate your help

Not much reason to book outbound and inbound flights together. That is to say I’d encourage you to book the flights as you see it become available.

I’m sure if you are happy to pay points + pay, you shouldn’t have any issues finding a seat. It’s reward seats that are harder to come by and cost a fixed amount of points.
