The departure of Kelly Bayer Rosmarin as chief executive will give Optus some clear air to move past the 14-hour outage, but for whoever comes next as CEO the turbulence won’t be over yet.

Bayer Rosmarin’s appearance at the inquiry into the Optus outage on Friday went fairly smoothly compared with how disastrous it has been for some to face the same fate in the past. Yet it was clear to everyone watching that she was unlikely to last much longer at the helm.
