I contacted Ryde library and they sent me a copy of the original record.

The email from her:
Hello Leanne
Unfortunately I have looked at the marriage entry and it does not give
you the information you require.
I have however attached it for you as there is other interesting
information you can glean from it.
Adolphe could write as he signed his name.
Elizabeth could not write (she signed with a cross)
The witness Catherine (sister? Mother? Sister-in-law?) could not write
as she too signed with a cross.
The other witness was George M Pope who was the local Registrar of
Births, Deaths and Marriages, Council clerk and census taker. My feeling
is that he may have been called in to be the second witness but may not
have known the couple personally.
