Small, but some growing/large tech companies. Canva, and SafetyCulture are probably the highest growth, Atlassian is already public and doing very well. Google has a Sydney office, Uber has some engineers scattered around.

Hopefully the government realizes they need to incentive tech workers with company share tax schemes, and startup tax cuts.

I know a few roles going in some of these companies; Python, Java, JS, Infra. Reply with an email address and I'll send through some contacts.
