With regard to the cutting and splitting of logs/forest discussion, I think both sides have merit, an un-caring chainsaw operator could do a lot of damage out there, and so I would hope we are all acting responsibly, (here's me saying that and I haven't tried it yet!), and I have split plenty of red gum, it can be split with an axe, depending on the log size and its texture, you just cut it across the rings, i.e. around the circumference, and its ideal for a cooking stove. All nighters need to be long and split across the middle (radially), either with a Canadian, or an Australian log splitter, they are different, a different angle on the head, or by using a wedge and sledge hammer.
As for the choice between a reciprocating saw, or a battery powered chainsaw, there seems to be equal arguments either way, perhaps angling towards the chain saw.
I have also committed the cardinal sin, by posting this on Wiki Camps, and the response there is also the same.
