If you put her name into RYERSON with date range 1878-1940 it gives 17 results, some of which obviously could not be her because of their age, but there are a few possibles.
Including one in 1880, plus one in 1887 aged 49 at Sydney, and one in 1882 at Narrabri, NSW aged 41.
Might be worth looking at
And you can search for those on TROVE, yourself.
