The 57-year-old The Living Room star shared an Instagram live story from Melbourne, where he is currently covering the Australian Grand Prix for Channel Ten.
TV chef Darren Purchese also shared a picture of himself and Barry at the sports event.
“Greet to see you here mate! Awesome to catch up with this legend @baz_dubois,” he captioned the image.
Barry’s fellow The Living Room co host, Miguel Maestre also shared a behind the scenes snap of himself, Dr Chris Brown and Barry filming next week’s episode of the Channel Ten’s lifestyle show.
Last year, Barry informed fans that he had been diagnosed with plasmacytoma myeloma and has been going through extreme treatment to try and beat the disease.
This is the second time the father of two has had cancer, with several tumours returning to his body in 2017. He had previously been in remission for six years.
