Dhu's assistant, Julie Harris, said sadness was weighing heavily on the warehouse's 30 employees. Staff had been granted time off from work tomorrow to attend Baice's funeral.
"We're all still in shock, people are only just getting their heads around what has happened in the last few days," Harris told the Herald on Sunday."We're still waiting to find out more about Yvonne's situation.
"All we know is that her daughter was young and had been in hospital since Tuesday. It seems like it was very sudden as Yvonne's husband called the warehouse that morning trying to find her at work. It's incredibly sad.
"A big group of us will turn out to say goodbye at Gus' funeral [tomorrow]."
Harris said Baice was married early last year and had a 1-year-old daughter. Strong Factory owner Dan Brinkley said the gym was Baice's "second home" and its members had also been rocked by the loss of its "gentle giant".
"Gus was the most humble guy in the gym," Brinkley said. "He was super-strong but he would always say how strong everyone else was. He was like a big kid, always smiling and super-happy. The nicest guy.
"Everyone knows and trains with each other. Gus would even come in on his rest days to hang out with people. The gym was his happy place."
A lengthy tribute to Baice on the gym's Facebook page signed off by saying: "It was an honour and a pleasure to have spent time with him. Miss you my brother."
Brinkley said the gym's regulars will turn out in force at tomorrow's funeral and they will be setting up an online collection for the Baice family.
"We've got some tribute shirts made up for him and the family. He would have wanted that."
