Looking for John Albert Skilton

Am looking my half brother John Albert Skilton, born 1933 in England & may have been living at Labrador, Gold Coast Qld, Australia between 1977 & 1980. He arrived in Victoria with his then wife, Ronalda Frances Skilton, nee Tullock in 1962. They divorced about 1972 & Ronalda was remarried to David Joseph Chrismas in Victoria & died at Frankston in 2001. As far as I know, John was a fitter or drill operator by trade. I don't know if they had any children, but would appreciate any help in locating John or any possible family he may have had.
