I can come up with another two major risks. Soveriegn risks i.e you are doing business in a country in Africa. Relatively stable on my research but still not the same as Australia.

Currency risks

However, if project was in Australia current stage my opinion would be trading 3 times what is now. i.e. discounted for Soveriegn risk.

If you have any other risks not factored in I would love to hear them, Always willing to listen to someone who may have thought of something I havent.

IMO it is always about assessing the risk.- Just because it is high risk it doen't mean I wont invest. It is a matter of wieghing the risks agains the return. Higher the sik the greater the return required to invest.
