The fiance and father of a three-year-old was working at a site on the Mitchell Freeway in Greenwood when he was struck by a concrete grate.
Breslin was rushed to Royal Perth Hospital but died a short time later.
Breslin was born and raised in Ireland’s north-west County Donegal and moved to Perth in 2011.
A message shared on behalf of Breslin’s fiancee Melissa, his son Tommy, and his family said he touched the hearts of many.
“He was always up for a laugh, whether it be greasing the door handles of a digger, giving yoghurt as sunscreen or being there to celebrate with his family and friends,” his family said.
“Duke was one in a million.
“He was a family man at heart and a loyal friend to many around him, he will be sadly missed but not forgotten.”
A fundraiser to support Breslin’s family has raised more than $587,000 since it was established on Saturday.
