I have sighted the second page, BUT NOT THE FIRST PAGE of the Vic marriage cert, as it seems to be available at one of the commercial websites.
Do you have the FULL certificate, as the information on the LEFT HAND (first page) should be giving you the places of birth for both the bride and the groom. As most of my families arrived before the gold rushes, (some even arrived before 1800) I am not much chop re Vic BDM records, but I am sure that there's two parts to their marriage certs.
