Yep, second that. I've built 3 new bikes in the last 12 months, all needed some work after riding a bit. One needed a new stem as the handlebar kept slipping after a while, really hard to find the right sized stem while out on the road and in the middle of a mass cycling tour. The second I had some issues getting all the parts together on time, went with what I had and suffered hiccups, had to pull out halfway through an Audax I had been looking forward to all year. And the third, I've had to order more parts as some components turned out not as compatible with each other as expected.
If you buy an off-the-shelf bike then you would expect that it might not be perfect but most bugs are worked out. Of course you'll need to have the bike ridden in a bit before you leave, to sort out what to take or not, make adjustments, do panic purchases of bits you think you might need. Cables will stretch, some bits like hub bearings might need tools to adjust that you won't want to carry on tour, all that stuff that pops up in the first month or so. If you're building a bike you've got less time for that whole run-in process. As it is it might take a while to find your perfect tourer, in your size and get it delivered. See what your LBS can get in, Fuji is just one brand that sells a readymade tourer, you might be able to get Globe, Cube, Specialized, Masi, Tout Terrain, whatever so ask. If you really want adventure you could just buy a secondhand tourer out of the Quokka/Gumtree/Trading Post and do some quick upgrading.
Are you in Perth?
