Sylvia I have just googled 'probate records Australia' and there are two possible sites for you - one NSW at www.records.nsw.gov.au/archives/early-probate_11821.asp
which will also cover Queensland up to 1859 -
and there is also a Victorian site. At present on Ancestry.com.au for $10 aud you can purchase a two week access to electoral rolls from 1903 to 1936 which I found really helpful in clearing up a few questions. Are you O/s? or in Australia?
