Another great guitarist here in Australia who would rival Tommy Emmanbuel is Michael Fix. Michael's website is at: http://www.ozemail.com.au/~mfix/
I've seen both perform live and they are pretty much equal. Michael is perhaps a little less the showman than Tommy, but then some would see that as good. There are many simnilarities in their style but it is hardly surprising as Michael was discovered by the legendary Tommy Emmanuel who became a mentor to the young guitarist and spent several years teaching and working with him.
The Folk Australia website has links to lots of festivals and great Australian folk musicians if you are interested in learning more. It even has access to a lot of CDs etc for folk artists in Ayustralia. http://folk.mountaintracks.com.au/Folk_Australia/
