Four helicopters are currently listed with Sea World on the Australian register. A pair of EC130B4, VH-XKQ and VH-XH9, which came onto the register as recently as 2 and 3 Nov 2022 respectively and which appear to be the helicopters involved in the collision. The others are both AS350B2, VH-SWL and VH-SWX, which had been in a different (blue) paint scheme.

Update: In that link they quote Jonathon James Spagnol on Facebook: “...Look like one went up and one was coming back in. Chopped the back off the other landed on the sand bar...,”. That account is consistent with the entire separated Fenestron and vertical stabiliser of the more severely damaged EC130 seen on ABC TV news footage lying close to where the other damaged EC130 had landed.
