The AMWU has been ordered to not block access by contract workers to the City West Water treatment plant in Werribee.
The Age reports that Tony Mavromatis, an AMWU organiser, and his union will be questioned in the Federal Court next month over the protests at the site.
Mavromatis has denied being behind protests, which are against the use of 457 visa holders from the Philippines being used by contractor Tedra. Mavromatis’s union was banned from the blockade, which has cost Tedra an estimated $1.5 million, yesterday.
Earlier in the week, Victorian premier Ted Baillieu said that the protests were part of a new trend in industrial action, where union-organised pickets were being disguised as community revolts.
“This picket has all the signs of a union picket that is disguised as something else," said Baillieu, likening it to protests last year at the Little Creatures Brewery site at Geelong.
The Australian reports that the behaviour of industrial relations consultant Grace Collier, who concealed a recording device in her bra to try and gain evidence of union wrongdoing, was also a concern.
"Ms Collier's conduct in that respect raises a serious concern as to whether she had breached the provisions of the Telecommunications (Interception and Access) Act," said Justice Stephen Marshall in the Federal Court.
