It's from 2001 and was even referenced in this group in 2004
Well. There's answering a question nobody asked...
You thought it was a new study. LOL
Abstract
Published and new samples of Aboriginal Australians
and Melanesians were analyzed for mtDNA (n = 172)
and Y variation (n = 522), and the resulting profiles
were compared with the branches known so far within
the global mtDNA and the Y chromosome tree. (i) All
Australian lineages are confirmed to fall within the
mitochondrial founder branches M and N and the Y
chromosomal founders C and F, which are associated
with the exodus of modern humans from Africa
≈50–70,000 years ago.
But you know for a fact this isn't true and even cited
discussions as far back as 2001.
If it isn't true then cite the RECENT research that shows
your claim to be true...
Are you insane? You can tell me. We're all friends here.

Revealing the prehistoric settlement of Australia
by Y chromosome and mtDNA analysis
Abstract
Published and new samples of Aboriginal Australians
and Melanesians were analyzed for mtDNA (n = 172)
and Y variation (n = 522), and the resulting profiles
were compared with the branches known so far within
the global mtDNA and the Y chromosome tree. (i) All
Australian lineages are confirmed to fall within the
mitochondrial founder branches M and N and the Y
chromosomal founders C and F, which are associated
with the exodus of modern humans from Africa
≈50–70,000 years ago. The analysis reveals no
evidence for any archaic maternal or paternal lineages
in Australians, despite some suggestively robust
features in the Australian fossil record, thus
weakening the argument for continuity with any earlier
Homo erectus populations in Southeast Asia. (ii) The
tree of complete mtDNA sequences shows that Aboriginal
Australians are most closely related to the autochthonous
populations of New Guinea/Melanesia, indicating that
prehistoric Australia and New Guinea were occupied
initially by one and the same Palaeolithic colonization
event ≈50,000 years ago, in agreement with current
archaeological evidence. (iii) The deep mtDNA and Y
chromosomal branching patterns between Australia and most
other populations around the Indian Ocean point to a
considerable isolation after the initial arrival.
(iv) We detect only minor secondary gene flow into
Australia, and this could have taken place before the
land bridge between Australia and New Guinea was
submerged ≈8,000 years ago, thus calling into question
that certain significant developments in later Australian
prehistory (the emergence of a backed-blade lithic
industry, and the linguistic dichotomy) were externally
motivated.
"These results indicate that Australians and New Guineans
are ultimately descended from the same African emigrant
group 50–70,000 years ago..."
