Lots of interruptions while having a look around my resources and many replies in the interim......so will post what I found anyway
One son's name -
OAKLEY, Albert Harold.
Burial 23 Nov 1931 Roman Catholic
Cemetery Lancefield cemetery, Victoria
and his death reg
OAKLEY Albert
Father Oakley John Mother Jane HAMILTON
At Lancefield 78 years 1931 Reg#14848
His birth does not appear to have been registered in Tasmania in 1853.
There is also this burial record
OAKLEY, Mary.
Burial 16 Jul 1938 Lancefield cemetery, Victoria Roman Catholic
and the death reg from the index
OAKLEY Mary
Father Reilly Edward Mother Mary UNKNOWN

And I wonder if this is another child
OAKLEY, Fanny.

Can't see a birth registration for Fanny in the Vic indexes.

No birth registration in the Victorian indexes for Leonard either.
Another
OAKLEY from the records but being born c1859 Vic may not be one of yours. May possibly be the son of Edward and Mary Ann HEWITT.
OAKLEY, Walter.

Have you considered chasing up some parish records...perhaps both Anglican and Catholic?
