Hundreds of rowdy union members have rallied at Melbourne's port in an ongoing picket that is threatening the delivery of goods ahead of Christmas.
Gifts, food and medicine may not be delivered in time for Christmas with a blockade at Melbourne's port expected to continue with a tense stand-off between unions and operators.
Hundreds of union members were bussed in to march on the Victorian International Container terminal despite the Supreme Court earlier ordering the Maritime Union of Australia (MUA) to cease picketing.
"You ought to be congratulated for defying these f***ers," controversial CFMEU leader John Setka told the crowd on Friday.
"We will continue to win. They're f***ing rats."
The stoush has been going for two weeks, after an MUA member was denied security clearance to work at the dock because of a criminal conviction.
Deputy secretary of the MUA Will Tracey said the casual worker in question had previously held a permit to work in high-security areas at the port despite the 22-year-old criminal conviction.
"We put a position to them if they just continue this person's employment without giving him shifts until he gets his permit back, that would be acceptable," Mr Tracey said.
The union member was sacked after raising claims of bullying and intimidation in the courts and his termination had nothing to do with his lack of security permit, Mr Tracey added.
However, a terminal spokesman said the worker had failed to be eligible for the permit and neglected to tell the company for nine months.
"He misled the company about his security clearance. This is not a fellow they want working for them," spokesman Michael Angwin told AAP.
Mr Tracey would not give a date on when the picket would end but said it was being run by the community and wider union movement, rather than the MUA.
The terminal says the action threatens more than $100 million worth of business, with one ship instead sent to Adelaide and others being diverted to alternative Victorian ports.
There are also more than 1000 shipping containers waiting for import and export, including $45,000 worth of pears, seafood, medication and milk for China, stuck at the picketed facility.
The company says it is monitoring CCTV to see if the action breaches the Supreme Court order and is considering its legal options.
