Chris Corrigan, the 1998 scourge of the wharfies, is back with a vengeance. If last week’s audacious stockmarket play succeeds, he will once again, after a decade’s absence, be a major employer on the rapidly-developing and increasingly automated Australian waterfront. Maybe that’s why his old enemy, the Maritime Union of Australia, is running, with its (declining) 11,000 membership (and its $40 million in assets) into the welcoming arms of its equally militant big brother (with about 100,000 members) and star turn at the Royal Commission into union misbehaviour, the CFMEU.
