And I can confirm visually that it was VH-OEB; I might have a photo or two of it once I start going through all the photos I took at the Grand Prix today. But for me, one of the highlights of the day was the F/A-18 flying around, one of these birds, which I shot at Tullamarine yesterday morning, definitely not a usual sight there:
