Now first things first: knowledge and experience in the building game will help, but can education help? Well yes of course it can and there are many ways to upgrade your skills. From the TAFE sector, there are dozens of trade and tech courses available, some short, others year long, all valuable especially if you are lacking in building experience. There are great Cert 3 courses including plumbing, roof tiling, carpentry, bricklaying, technical engineering, building and construction, formwork, scaffolding, glass and glazing, drainage, owner builder compliance, site management, building surveying, plastering, tiling, concreting, painting and decorating, waterproofing and flooring. Any one of these will allow you to DIY or ably assist trade workers on site. And don't forget Project Management and WHS. Explore this more here...

Some providers are better than others. Websites are the first port of call. Look for an OB support page, information on supplied building manuals and testimonials that have links to OBs willing to talk about their experiences. A phone or email link to the provider who can guide you through the more complex sections of the build is imperitive.
This site has many OB support ideas: just click the Owner Builder Nav button at the top of the page or below and explore there too.
