Pioneering Australian tech entrepreneur Simon Hackett has invested $1.5 million to purchase a quarter of graphite miner Oakdale Resources’ initial public offering, predicting a clean energy tipping point will be reached in the next five to 10 years.

Aeeris, the company that operates Australia’s only national location-based weather and hazards early warning service, is seeking to raise $6 million through an initial public offering (IPO) on the ASX.

The cofounder of Australian IT DevOps company ScriptRock, Mike Baukes, says an open mind is the key to getting the most out of startup events such as Tech23, which can be an important networking opportunity for emerging entrepreneurs.
