Quite an achievement, given that he'd have to circumnavigate South
America to get from Miami to the Pacific Ocean.
It's unlikely that he reached land at Cheviot Beach. A look at the
region south of Melbourne will show why. Port Phillip Bay is a large bay
-- the largest in Australia, I think -- with a relatively narrow passage
to the open sea. When the tide is rising water has to rush into the bay,
and conversely on a receding tide. The resulting currents add up to a
lot of moving water. I don't know whether anyone has mapped it, but I'd
expect major circulating currents south of the bay.
Just east of that you have Western Port Bay, another tidal bay. (And no,
I don't know why it's not called Eastern Port.) That is semi-blocked by
Phillip Island, a popular tourist destination, whose beaches display an
interesting phenomenon. On the north side you have a gentle sea typical
of a bay. Just a short distance away, on the southern side of the
island, you get the savage waves of an ocean beach, in the treacherous
