WOW! Thanks, Tosh.
With the residence requirements, I can see this is firmly aimed at the Australian diaspora. Fair comment also, regarding the likelihood of the pilot not wanting to pay the tax if he can get away with it (natural pilot trait!) But it leaves him totally exposed to SIA spilling the beans on him later; another lever of control.
Sounds like the best option is for guys only to apply for 'proper' SIA jobs. If SIA then want to base pilots elsewhere at, that must be negotiated with ALPAS.
Also only to apply to SIA once the salary package and current disputes are resolved!
Fly safe!
