Ferret,
More practically, for vacancies look on
www.aviationjobsearch.com or
www.totaljobs.com
Salaries here vary enormously, I suppose the industry standard must be round about £20k, but there are companies paying as little as £12k, and of course companies paying more (Don't know what this works out to in Oz money).
Bear in mind living costs here also vary enormously - the nearer you get to London, the more expensive the property.
If you're determined to come here, Good Luck!!
