Hi there,
I'm Paul - mostly English but living here in Northern Ireland where we get all of the weather, sometimes in very quick succession, so we do what astronomy we can in the gaps in between what's blowing off the Atlantic!
Have been to your part of the world many times - Aussie 8 times between '87 and '03 and NZ '97 and '03. Was at Ceduna for the eclipse 2002-12-04 which got me hooked enough to be in Turkey last year. Best eyeball sighting ever was in SA on the 2002 trip when a chap from the ASSA showed me 47 Tuc through a 15" Dob - Awesome!
This time in May it doesn't get dark at all - there's a blue glow all night as the Sun is not far at all over the other side - it's NLC season!
Here's a sample image from my house in Larne last June....

Needs to be zoomed in and panned across.
Clear skies all,
Paul.
