Not everyone has access to Ancestry
May I suggest you have a browse through the Resources Board for Australia and each State individually. I treat online trees with caution unless well referenced and all sources noted. So many are simply copied and pasted, errors included.
To start your research you can search for Tasmanian information including links to digitised convict records here
http://portal.archives.tas.gov.au/menu.aspx?search=5The Tasmanian bdm's are not online although there are transcribed records on the above link.
