Yep. I don't know if it's a 'trick' or 'tip', but if you call the guest service number between 9am and noon AEST, you usually get put through to their Manchester call centre, and I've always found them excellent. I have no idea why I have this impression, but it really feels like they're much more empowered to do stuff for you...which is nice given Etihad's call centre staff are usually utterly hopeless.
The guy I got last week literally read out a full list of flights on the days I wanted - checking later on Virgin's own site I think there was only one flight option he couldn't offer me. The flights were $1850 each way online, but cost ~22000 points each way. Pretty sweet deal.
