Do you have information re Elsie? The information I can see shows that, unless there is someone else of the same name at around the same time in Victoria, she continued to use the surname Buldt for all of her life.
Death:
Reg: 1955, Victoria, number 12342
Elsie May Buldt, 67
Death Place: Chel, Victoria ( presumably Cheltenham)
Father's name: Mungo Broil
Mother's name: Elizabeth Peel
Probate granted:
Name: Elsie M Buldt
Died 27 Oct 1955, at Cheltenham Home
Occupation: Widow
Grant Date: 7 Dec 1955
Grant: A (Administration)
Marriage:
1911, Victoria, number 1810
Name: Elsie May Beown [Elsie May Brown]
Spouse: Hy Buldt
She doesn't seem to be with Tom on the electoral rolls:
1914
with husband Henry at 89 Napier St, South Melbourne
1917 - no-one else of that surname at that address in 1917 or later
at 66 Clyde St, St Kilda West
1934 - 2 entries
at 42 Clausen St, Fitzroy North
also at 89 Park St, Carlton (also ij 1935)
There are no further entries under that name until -
1949
17 Chestnut St, Oakleigh
1954
address is shown as: M.H.A., Cheltenham North - not sure what these initials stand for but the probate entry suggests it may be some kind of care home, but maybe not.
TROVE has this:

In Victoria, widow, deceased, intestate, may be granted to Ethel May Turner, married woman, of 32 Boston av., - East Malvern, being the daughter of
