Remind me again what unicorns Australia has? Atlassian is not one of them, having left due to AusGov being so anti-startup.
We are technically a UK incorporated company, headquartered and half our staff in Sydney and many of our staff and customers in the USA.
I still consider us Australian though.
I see many clever companies where I live in Melbourne - however I am saddened by what I perceive as the neglect the government is showing for the tech sector, especially startups; I'm looking e.g. at how share options are taxed. I believe there's a lot of lost opportunity here.
