Easts get , and keep whomever they want , you don’t decide to leave you are just booted when they’ve had their fill.
The Easts system is one that sets you up for life , it’s why they say “ they sign for less “ , and don’t know about less but a gig there at say $600k is worth a lot more than a gig at Manly for $850k because of the massive lifetime benefits.
I don’t know exactly but it’s what I hear.
It’s why there are so many more ways to skin a cat than purely $$$$$
More money means more tax , and a lot more tax , less money and a range of benefits is far far more tax effective.
