Melbourne has been lauded as the nation's technology capital as global giant Google unveils its new office in the city.

"We're working hard to retain our number one tech city ranking in Australia - we believe Google has both a bright future here and a strong part to play in delivering strong job growth," Victorian Innovation Minister Philip Dalidakis said on Thursday.

Google Melbourne site lead Sean McDonell said the hub had grown from four people a few years ago to having more than 100 desks in the Melbourne office.

Google is one of the many tech giants investing in Melbourne alongside Alibaba, Amazon, JD.com, LiveTiles, Mimecast, Slack, Zendesk and Square.
