Backpacking around NZ, Oz & Asia for 6 months

I have had several point and shoot compact cameras in the past. I also have an entry level fuji film digital SLR but I have to admit that I mainly use this on auto mode. I have good basic skills in composition and photo editing as well as timing for capturing action shots ( a lot of time spent photographing horses!)

I need a rugged, durable camera that I can take out and about with me on my travels, whether I'm hiking , snorkelling or out at night. I'd also like to be able to take good scenic shots and some close ups. The camera needs to be easy to use as with what I'm doing, changing settings all the time may not be possible. 

One thing that i find annoying with my current Samsung compact camera is the speed. 

Looking forwards to hearing your advice :)
