Welcome, Nick. (Pay no attention to HB, who's just upset 'cause most of us aren't sure where Canada is.)
There are some particularly sensitive professional framers here (and I'm not implying that HB is one of them - I might be one of them) who may resent the suggestion that you can learn framing from a book. Most of us old farts learned by trial-and-error or by working with someone else who learned by trial-and-error.
Avail yourself of some of the excellent educational opportunities which must surely be available even in the outback. Find an experienced (and self-confident) framer to mentor you. If there is a trade association in your area, consider joining it. Go to trade shows. Read The Grumble (and take everything you read, including this, with a grain of salt.)
In the meantime, you ARE a DIY framer, so don't thumb your nose at those books. There is information to be gleaned from a variety of sources.
