Sydney
Sydney’s world-famous Opera House was lit up by a spectacular fireworks display to see in 2019.
Millions witnessed the extravaganza of light and sound at the stroke of midnight local time (1300 GMT).
Dozens of pyrotechnics erupted from the city’s Harbour Bridge, with breathtaking aerial shots showing the scale of the celebrations.
Auckland
It came after New Zealand welcomed 2019 with a glorious fireworks display which erupted from the top of Auckland’s 328-metre-tall Sky Tower.
Thousands of revellers on the city’s waterfront watched brightly coloured fireworks and laser lighting shooting into the night sky over the harbour.
The Sky Tower show – featuring 500 kilograms of pyrotechnics – is the highest fireworks display in the southern hemisphere, according to Auckland’s council.
And for the first time, Auckland’s harbour bridge was lit up by special lights.
Samoa and Tonga
Samoa and Tonga in the South Pacific Ocean were among the first nations to see in the New Year.
Meanwhile, photographs from other nations showed local celebrations.
Dubai
The UAE rang in the New Year on Tuesday (January 1) with a colourful light show and firework display centred on the iconic Burj Khalifa in Dubai.
The fireworks display was suspended last year due to “security concerns” at the tallest building in the world, moving instead to the Palm Jumeirah, an artificial archipelago extending into the Persian Gulf.
Moscow

President Vladimir Putin called for unity across Russia in a New Year’s addressed televised on December 1.
Putin said that the country had to create a brighter future through its own united effort, highlighting “problems” in the spheres of the economy, science, technology, healthcare and culture.
The New Year’s address was broadcast to Russia’s Far East regions many hours before Moscow, when it is typically shown minutes before midnight.

London
The words “London is open” rang in the new year as the capital welcomed 2019 with a dazzling riverside fireworks display.
The phrase was spoken in seven languages around two minutes past midnight as the city skyline filled with lights in the largest annual display in Europe.
A soundtrack featuring Europe’s finest musical artists celebrated the diversity of the capital, after Big Ben, silent for much of 2018 due to renovations, chimed once more.
