have a twin, which they (IIRC) originally purchased for the very reason that it was a better proposition for the ship operation
Because the CP found that NSW Fire Ops is more attractive, the status quo returned to the 407 doing ship ops and the EC-145 contracting for fire fighting, instead of the other way round

FWIW, the 407 seemed to perform well enough back when it was used in NSW, no major issues with performance or with bucket lifts. But obviously a shiny new glass cockpit 145 is a major attraction, especially for all those dusty paddocks
