Are there any large tech conferences/events in Australia?
My answer to Are there any large tech conferences/events in Australia? on Quora
Web Directions South is a big Australian web event—you’ve just missed it though, it was a couple of weeks ago: http://south11.webdirections.org/ ( http://lanyrd.com/2011/web-direc... on Lanyrd). It’s along the lines you describe, although tends to be more developer-focused than business-focused.
We have a list of upcoming conferences in Australia here, most of which are technology related—you might find something interesting in there: http://lanyrd.com/places/australia/
