It's a matter of hours until 14 tonnes of fireworks shoot into the sky over Melbourne to ring in the New Year.

Months of planning have gone into the show that includes 8300 aerial fireworks and more than 36,500 rooftop effects being fired from 22 CBD buildings.

The innovative 10-minute show has an indigenous theme and is set to a backing track by Australian rapper and hip-hop artist Adam Briggs that will be broadcast on 99.7FM.

More than 350,000 revellers are expected to flock to the city to welcome the new year at riverside bars and parties, and from four family-friendly live sites.
