Jaygandi what is happening to Qantas in Tasmania is that the main airline (Qantas domestic) is handing over all flights to and from the state to regional airlines, these regional airlines operate under an umbrella brand called QantasLink. Qantas still manages the marketing (including branding, uniforms etc) and makes network route decisions for QantasLink, and the airlines also fly with a QF flight number.
In Tasmania two companies will operate these QantasLink branded flights - Eastern Australia Airlines and Cobham Aviation Services.
Eastern is a wholly owned company belonging to Qantas, but has its own management, staff, operational procedures and aircraft (Dash 8 variants).
Cobham is an independent company, with its own management, staff and operational procedures, but uses aircraft which are owned by Qantas (Boeing 717).
In regards to training: Typically regional airline technical staff have less experience than the technical staff of their mainline operators. One of the career progression routes available for technical staff at an airline, is to go from regional operations to mainline operations as they gather more experience.
