Events were underway in Australia and Hong Kong on Sunday to mark the 100th anniversary of the end of hostilities in the First World War.

In cities across Australia, including Adelaide, Brisbane and the capital Canberra, Australians gathered to remember those who lost their lives during World War 1, also known as the Great War.

Veterans and citizens gathered at various Remembrance Day events, in which commemorative wreaths and red poppies, the symbol of First World War remembrance for Commonwealth nations, were displayed on monuments and at cemeteries.

In Adelaide, aircraft released thousands of poppies over ceremonies being held on the ground, while in the capital Canberra, prime minister Scott Morrison and opposition leader Bill Shorten reviewed the Roll of Honor which was covered in the bright red floral symbols.

"Those who fought in the Great War had the same normal flaws and frailties of any other Australian. Yet their selflessness at the darkest of times has set them apart for eternity in our nation's consciousness", Morrison wrote on Twitter.

More than 60,000 Australians died during the four-year conflict, one of the deadliest in history. Approximately 37 million soldiers and civilians perished during the war.

In Hong Kong, a former British territory, hundreds of people gathered to observe two minutes of silence at the Cenotaph war memorial.
