Many flags will be lowered to half-mast in recognition of the National Day of Mourning on Sunday.
The day commemorates workers who have died, been injured, or suffered illness from work-related incidents.
It also honours the families and friends who have been affected by these tragedies.
Events are taking place in many communities across the country to commemorate the day.
The National Day of Mourning was first launched in the 1980s and was officially recognized by the federal government in 1991.
