For a bit of context, according to jetcraft.com there have been 123 G150s produced in total since they began production in 2005. There would likely only be a small number of Pilots (relatively speaking) that have time on this type then, snagging one that is currently looking for a job, current CASA Class 1 Medical (So not flying overseas for the last few years), right to live and work in Australia and willingness to locate to Darwin seems like a needle in a haystack but good luck to them!
