Thanks all for the details on how the process works.
sorry for inferring jandakot was regional- having lived in Arnheim land, Cloncurry, Mt Isa, Port Augusta, and Murgon over the last 15 years, I would much rather have lived in Perth! That said, these days one has a growing family and looking for a little more stability and predictability. Sounds like enroute would be the better decision for me, should I get the option.
cheers and thanks again.
