Thanks again gentlemen,
Sunny Hill looks to be the go as I can get it to Oz with an import permit. As you have pointed out Jonathan cost may be there but in the long run safety is paramount and having it right the first time is much cheaper in the long run!

I went out on Thursday and Friday with my dad into Arhnemland and I'm glad I have the 404, 338 Winnie's are good but a 404 is definately a good deal better on bulls on the paper bark.

Stay safe, MOG
