Birthplace of Josephine Alphonse Shaw

I only know she was born in 1903 in ? Victoria. Her parents John Francis SHAW & Ellen GALLAGHER were married in the RC church in Hamilton, Victoria & at a later stage lived in Mount Gambier. I'm interested to know where in Victoria & if perhaps the family moved elsewhere before moving to Mount Gambier. She was later the 1st wife of my father Gordon Henry BURNS, born in Edenhope, Victoria. They were married in 04/02/1920 & lived in Mount Gambier until she passed away in St Vincent's hospital, Melbourne, Victoria.
Any small missing detail appreciated as it fills in significant part of my father's life too.
