Hi there, you won't really find many LAME jobs on SEEK but try the link below. Occasionally there are some jobs there
Airline Pilot Jobs & Pilot Employment - Rishworth Aviation Recruitment Specialists
Also, Fridays version of "The Australian" newspaper has an aviation section in it. There is occasionally LAME jobs advertised there. However, I'm not sure if the on-line version has the job ads posted.
alternatively, you can do internet searches of various operators around the country and view their jobs sections.
Hope that helps
Bort.
