The white panel on the old red Virgin Blue livery is clearly visible - there are suggestions that VH-ZPL and VH-ZPO (which is the other aircraft) may soon be repainted into the Virgin Australia livery.
UPDATE! VH-ZPL was noted at Mackay Airport on Wednesday 10 April as well!
Incidentally, Virgin Australia E-190 VH-ZPN has recently left Australia to be repainted into Virgin Australia colours. VH-ZPN did wear the colours of Pacific Blue - Virgin's former New Zealand-based off-shoot.
