Well, I can now give it to you "from the horse's mouth". Here is the text of the reply I received this morning:
"
Yes, it is cancelled for 2010 for reasons stated on our Internet site (
http://www.arkaroola.com.au/starparty.php) - i.e. maintenance required at Arkaroola Village.
I did advise the editor of the Aust. S&T magazine, but it would appear that notification was not in time for the latest edition - thank you for bringing that to my attention - I'll certainly chase that up first thing in the morning (Monday 9 November).
Again, I do apologise for any inconvenience this may have caused."
So that, as they say, is that.
