Using Continental OnePass Miles on Virgin?

I am trying to book from LHR to SYD or LHR to HKG on Virgin in Upper using my Onepass miles. This is for a flight in September this year.
Does anyone know why Continental aren't showing availability? I have always been told to book reward tickets early, but is this too early.
The Continental lady didn't know and she advised I call Virgin/
Any thoughts would be most gratefully received.
Thanks in advance.....
