Following up on Rita DEMAS and the earlier posts re the electoral rolls and NSW BDM 1906 ...
From NSW Electoral Roll for 1903, SOUTH SYDNEY, polling at Alexandria (first time females enrolled to vote, the two different addresses could simply be that Lizzie enrolled for that first female opportunity and that Leo had not yet updated his earlier address, but that suggestion is really only speculation on my part)
Leo J DEMAS, 8 John St, a tailor
Lizzie DEMAS, 8a Pickup St, domestic duties
From Sands Directory Sydney Alphabetical 1905
HOEY:
Henry, 28 Dickson St Newtown
Mrs J, 41 Short St Balmain
John, 4 Zamia St Redfern
Robert, 1 Union St Balmain
Cheers, JM
