Sydney Harbour has been set ablaze with light, colour and music as another dazzling fireworks display thrilled capacity crowds from around the world and marked the arrival of 2017.

After a year that many were happy to leave behind, an estimated 1.5 million people packed the foreshore on Saturday for a double bill of fireworks climaxing with the world famous midnight pyrotechnics extravaganza.
