Pelair has obtained a couple of B350's for its NSW air ambulance contract, probably have more on order or perhaps have options for more to fill demand over time.
I've seen the RFDS PC-24 go into Essendon twice over the past few weeks, so they are clearly a contender.
Without seeing the tender request, I'd put money on Pelair with their existing B200's, which would then be phased out mid contract to B350's presumably...?
