Thankyou all for your replies It has been a couple of years since I originally started my research so thankyou for adding the link to my original post. I dont have much information on my grandfather at all but here is what I do have:

Death:
Record of Death William Walter Heighway. New South Wales 6467/1967 HEIGHWAY WILLIAM WILLIAM WALTER UNKNOWN SYDNEY. Note William Walter was also given as father's name, mother's surname unknown.
His wife died aged 77 in Liverpool in 1988 as Phyllis Heighway.
The William Walter Heighway born 1889 was his father.
I do have his marriage certificate to Phyllis Lubeck which contains the following details:
Date: 15th June 1940 Marriage solemnized at The Register Office District of Liverpool South in the County Borough of Liverpool William Leslie Walter Heighway, Aged 27, Bachelor, Motor Mechanic, 40 Leopold Road, Liverpool Father: William Walter Heighway, Ministry of Labour Clerk Phyllis Lubeck: Aged 19, Spinster, Confectioners Shop Assistant, 40 Leopold Road, Liverpool Father: Philip Lubeck, Seaman Merchant Service Witnesses: A Kirk & E Smith
His father's sister was Florence May Heighway emigrated to Australia in 1914 and married Charles Alfred Saunders in 1922. I do have their marriage certificate also..usual place of residence Paddington and marriage in Waverley NSW
Also in 1922 his grandmother Martha Heighway emigrated to Australia (the year Florence got married)
Hope this information helps as I dont think the William living in Bondi could be the right one after all
