Bit More,
(remembering it was NOT compulsory to enrol, but that 1903 NSW rolls included for first time, women aged 21 and over, and there was no longer any "property" requirements to be eligible to enrol, also neither the AGE of elector nor if married/single/divorced etc indicators were ever noted )
1903 NSW Inverell polling place.... Susan, I'm not sure if these surnames have any bearing on your chap)
GARRATT, Elizabeth, domestic duties, at Inverell (no street address shown)
GARRATT, William, senior at Greaves St , labourer
GARRETT, Catherine, at Arthur St, domestic duties
Cheers, JM
