You can remove KPMG, Deloitte and PwC from that list, they don't like high-schoolers anymore
You've missed plenty, opportunities are literally infinite, I can provide you with nearly everyone I've applied to/know that have Cadetships for this year, I'm not sure about next year though. Side note: I don't recommend Boroughs the slightest bit, the most boring people and old-school you'll ever meet.
List (no order):
- EY
- BDO
- UBS (Professional Cadetships - Business)
- Pitcher Partners
- Hall Chadwick
- Nexia
- HLB Mann Judd
- RSM Bird Cameron
- ESV (on request) lol
- Bentleys
- Mazars
- Crofts (super small - located North Sydney)
- Bachelor of Accounting (Co-Op) -> UTS
- Moore Stephens (not entirely sure if they still offer)
- Grant Thornton (again not entirely sure)
- UNSW Co-Op
p.s I've no idea who champions are
If you want an idea of the companies I recommend, and the firm I'll most likely choose for next year from my offers, pm me.
