Members of the Electrical Trades Union (ETU) reiterated they will not return to work at the Brisbane Airport Link unless a safety audit is carried out to ensure their safety and the structure's stability following the death of a co-worker last Thursday.

More than 500 workers met Tuesday morning and agreed not to return to the job at least until Thursday, or until all their safety issues were properly and sufficiently addressed.

Sam Beveridge, a 40-year-old worker and father, last week died after a falling beam struck him in the head at Lutwyche. The worker died in the hospital that same day.

Workers will return to the site for briefings but will not work until after the audit is completed.

''We'll have a list of areas to be rectified and hopefully we will start on that tomorrow morning," ETU spokesman Peter Ong said to The Sydney Morning Herald.

The $5.6 billion Airport Link is by far Australia's largest road infrastructure project.It will connect the Brisbane's central business district with the Clem Jones Tunnel and the East-West Arterial Road leading to the Brisbane Airport. It is planned to open by mid-2012. It is the longest road tunnel system in Australia, with 5.2km of its 6.7km-length underground.
