Australia Welcomes the 2015 with a Bang.

Millions of revellers across Australia just experienced a taste of what is to come at midnight as the iconic Sydney Harbour lit up the night sky in preparation to celebrate the countdown into 2015.

The traditional prequel to the midnight annual spectacular – the 9pm firework display is particularly suited to families whose young children will be in a deep slumber by the time the clock strikes 12am.

Two bright blue seahorses were the stars of the first act of the city's renowned fireworks display as the Sydney Harbour Bridge once again stole the show. 

Never an event to disappoint – both fireworks displays feature a total of seven tonnes of fireworks, including 11,000 shells, 25,000 shooting comets and more than 100,000 individual pyrotechnic effects.

Following the 9pm display, the Harbour of Light Parade will see more than 50 illuminated boats carry over 8,000 people on a majestic passage around Sydney Harbour.

And as if that wasn't enough - a third mini-display, known as the 'Inspire moment', kicked off at 10.40pm to keep crowds entertained in the lead up to the much-anticipated countdown.
