https://www.bdm.vic.gov.au/research-and-family-history/search-your-family-historySue also found some other births which may be siblings for Mary.
1856/2866 BURNE Thomas, Parents William and Bridget BURNE, Back Creek
1873/3057 BURNS, Edward, Parents William and Bridget BURNS, Huntly
These three births are in/around Bendigo, Victoria. Mary lists her birth as "Reedy Creek, Victoria" and yes there is a Reedy Creek in central Victoria, near Broadford - however there is a Reedy Creek which is a suburb of Bendigo. IF these births are related then I suspect that Mary's birth may have been the Reedy Creek near Bendigo.
