Its an exponential increase. With higher level jobs commanding the highest rate of appreciation.
Analyst ( i think they have 4 levels)- starting from 45k AUD or so to about 65k
Senior analyst 65-75k or so ( i think they have levels here too)
Snr managers 100-120k
Directors ( i think 3 levels) 120-300k
Partners ( i think 2 levels) - if you have to ask...you are not getting it...400-700k range + bonus of all kinds.
I think the bonus structure applies to anyone manager and up.
The big 4 are made up of the junior ranks. Many worker bees and few snr managers/directors.partners etc..
PWC AU has mixed work- some good gigs, and some average ones, as with all consultign companies. Networks are vital too.
