Didn't realise that. Have never heard them doing an RNP approach anywhere it makes sense to do so (05 ADL, 19 BNE, 15 CNS, 34 MEL etc).
As mentioned Virgin only fly the publicly available RNP-AR approaches published by Airservices. At present these are limited to Gold Coast RWY14, Maroochy RWY 18 and Ballina RWY 06 & 24. I'd presume operation to available minima with RNP <0.3 will occur with CASAs approval.
