Singa,
ASA are desperate, I think the real reason that they have gone cold on the O/S recruitment is the knockbacks they have been getting.
O/S controllers, who are displacing themselves and maybe families, can do a hell of a lot better elsewhere.
They have just substantially upped their offers to entice RAAF (our airforce) controllers over.
I doubt you would get Adelaide but I wouldn't be shy in contacting them and letting them know of your interest.
