Sorry Martin, I've never been out of Australia.
But I have seen Aurora Australis.
Twice in my childhood, once as a teenager and once as an adult.
The adult time was only 2 years ago from here in Snake Valley (seen by 3 of us on a club night - me, Bryan [Lowai], and 1 other) and was really faint and unimpressive, but still exciting.
The other 3 times in my young years were actually seen from the far western suburbs of Sydney! (which is amazing in itself)
The two times in my childhood were pointed out by my Dad and were pink and green.
The one in my teens was very pale green.
I was awestruck for all 3.
I really hope you get to see some spectacular Auroras.
They really stay imprinted on your memory
