Deloitte, EY, KPMG, PwC probed by ACCC over cartel conduct

One aspect I found amusing was the following comment attributed to PwC:
"Late last year, we received an information request from the ACCC and we have been working with the regulator since that time." "Working with" must go down as one of the greatest euphemisms of all time - companies don't "work with" the ACCC in relation to a potential criminal cartel investigation.
