Rather than spend the $20.00 for the Vic certificate, I'd wait to hear back from the church archivist.
In the meantime I've traced Christian Smith (nee Robson), her son C R L Smith, and daughter Christian (married Horace W Taylor) to Henty, New South Wales.
Charles Robert Lumsden Smith served in WWI. He died at Henty, 1929.
12478/1929 SMITH CHARLES R L WILLIAM H CHRISTIAN HENTY
NOK: Mother, Mrs Christian Smith, Day Street, Henty, New South Wales.
This info 'may' come in handy for anyone researching George and Eliza's family.
Cheers, Anne
