Atlassian started in Australia, a country where technology is generally considered a scam to separate idiots from their wallets. This significantly slowed down growth, and the founders have said they wished the company had left Australia sooner.
Edit: this went from +2 to -2 very quickly. For anyone unfamiliar with Australian technology industry, here's a reference for Atlassian CEO comments: http://www.computerworld.com.au/article/557248/atlassian-ceo...
The Australian government also taxes employee options in such a way to make them non-viable: http://www.techworld.com.au/article/535906/what_atlassian_mo...
My own experience working in Australia (as an Australian) in innovative technology was extreme wariness of tech: it's an expense, not an investment. Local companies were cynical of technologies, even mainstream technologies in the US and UK, until there was at least one other Australian company using them.
