I think it's a great idea and by the time you get to Oz I shall be back living in Perth. You are most welcome to come for a visit and a stopover. I ran into a Brit called Adam Lewis who is doing the same thing on a BMW single. He's been most everywhere. Look up his story on the net. Just look for "Short way round". He stayed with us here in Geraldton for a few days and we had a great time.
Re the preparation, I agree with lots of what Hobot had to tell you with just a few variations. Building a bike to suit rather than buying something already done is much preferred because you never know what you are getting. I would never buy another Commando that was complete and running. I now have a pretty good idea of what mods are essential and which ones are useless/unnecessary. Someone suggested radical mods where I would suggest keeping it pretty standard for the sake of ease of maintenance/repair.
Good luck.
