The 40-year-old diesel mechanic shaved his beloved beard on Friday during a fundraising barbecue at Andy's Earthmovers.

Staff at Andy's Earthmovers raised about $2500 to donate to former workmate Andrew Manning.

Mr Manning's two-year-old daughter Georgie has been diagnosed with primitive neuroectodermal tumours, a rare cancer characterised by clusters of tumours on the brain and spine.

Georgie is in the Royal Children's Hospital and Andrew has moved his young family from Bendigo to Melbourne to be closer to the hospital.

Andy's Earthmoving human resources coordinator Kristen Simpson said staff were organising another fundraiser this week and aimed to raise another $500.

"The shave was lots of fun," she said.

"Sam's kids came and they put the shaving cream on his face and everyone was laughing.

"He made a nice little speech saying they couldn't imagine what it would be like to be in that situation."

Meanwhile, thousands of people turned out at the weekend to support a market organised for the family of Georgie Manning.

Organiser Tegan Baines, who is Georgie's aunt, said the market raised more than $25,000.
