The chief executive of Optus has made a surprising admission that the telco overcharged customers for many years, describing the industry behaviour known as "bill shock" as "crap" and "immoral".

At an end of year media party in Sydney on Thursday night, Kevin Russell said Optus had taken a "really serious" stance on the practice, whereby a customer runs up a costly mobile phone bill by using too much data or calls, particularly when roaming overseas.

[As an industry] we know that if [customers] don't complain we'll get an extra whopping bit of revenue.
