About 10,000 workers rallied in Melbourne on April 30, demanding better safety on Grocon construction sites.
The rally marched to the Grocon-owned site in Swanston street where a wall collapsed onto a public footpath in March and killed three people.
The march then moved to another Grocon site where a crane operator was killed earlier this year.
Protesters demanded industrial manslaughter laws for bosses be introduced.
