This is getting ridiculous!
On Wednesday 2 March, Queensland Government (QGAir) Rescue (State of Queensland) Agusta AW139 helicopter VH-ESH flew North from Archerfield to Cairns via Gladstone, Mackay and Townsville Airports.
VH-ESH has been operating around Brisbane and the South-East corner of Queensland as "Rescue 500" right up until Tuesday 1 March.
This is the fifth day over the last week or so when a QGAir Rescue helicopter has either ferried North or South (presumably) as a part of a maintenance 'rotational system' which is reportedly designed to ensure the even distribution of flying hours on each of their helicopters, thus avoiding the need to have multiple helicopters offline for simultaneous scheduled maintenance.
From what I can ascertain:
AW139 VH-ESZ flew North on Wednesday 24 February and then flew back South on Tuesday 1 March.
AW139 VH-EZJ flew South on Thursday 25 February.
Bell 412 VH-ESD flew North on Friday 26 February (joining Bell 412EP VH-ESB in Townsville).
AW139 VH-ESH flew North as above on Wednesday 2 March.
