Hi,
Can't help much with tracking Alfred, but it seems he was dead by 1948 when his Sister Eliza CALDWELL died.
Her 1948 death notice says-
...survived by ...... and an older sister Mrs Ann FAIRBAIRN of Preston.....

Thanks Saddles I know his son William died Nov 1924 at Healesville not sure were he is buried but his wife Amelia Emma died May 1932 and she is at Box Hill Cemetery. Take Care Lynette 
This funeral notice for William BURTON jnr states Healesville Cemetery. The cemetery staff, I am sure will assist with whatever omission or error has occurred on their online register.
http://trove.nla.gov.au/ndp/del/article/2072001 Amelia is, as you say, buried at Box Hill Cemetery where she is located with a chap with whom she shared an address from at least 1931.
He was born in 1882
