DNA testing strategy for Australians
Australians are taking commercial DNA tests to- find biological parent/parents, solve family mysteries generally who's my great-grandfather to great-great-grandfather, verify their genetic pedigree (and often finding it's not the same as their social pedigree) and establish ethnicity. Louise Coakley (aka "genie1") is an Australian genetic genealogist with an excellent website. You can read about genetic genealogy HERE. Testing at any of the major commercial DNA companies gives useful ethnicity estimates. However, if you're testing for any other reason, my first step would be to take an autosomal test. Often called cousinship tests, you'll get matches across all your ancestral line. They're offered by all the major commercial companies but there's a definite path I'd recommend- testing at AncestryDNA which has the largest data base and most Australians test here, downloading your AncestryDNA data and upload it to MyHeritage, FamilyTreeDNA, Li
