About Who Dares

A solutions-driven company

The principle of daring to succeed underpins everything we do. The company drive and ethos has come from the founder Rangi Nicholls, former officer of the New Zealand Special Air Services. In 1986, the motto ‘Who Dares Wins’ applied to his aim of daring to take on the next big challenge – to create a company that provided a range of special services to the Australian film industry. Since then the company has blossomed to cater for a huge variety of events, transport and government clients whilst still keeping strong ties with the creative film industry.

From coordinating rolling blocks of the Sydney Harbour Bridge to closing city streets for Pacific Rim Uprising (2018) to overseeing traffic operations for Sydney Mardi Gras Parade, City2Surf and VIVID Sydney, we have got you covered!  Our Managers will work with you to deliver your project.


Glenn and the team … a faultless job from beginning to end and sincere thanks to everyone involved.
