Dazza this website has the Safari tent which is basically identical to the Southern Cross, but is 11' 6" x 8' 6" x 7' high instead of 10' x 10' and they say is far better from utilisation of space and layout with the rear extension. Looked good and well made as it was next to me where I camped over Christmas. Why I took note of it as it looked like a better design.

Also try Boots Great Outdoors. They price well, and typically the staff are pretty knowledgable.

I am the original referrer to Peter hands at Express Tools and Camping. He is extremely helpful, offers good prices and knows his stuff from Swags to kimberley campers. I have the next size up of this tent and it is great
