Only 13 years and seven months after Australia’s Federation, our young country went to war.

A Commonwealth we were, but a people still primarily defined by the states to which we belonged, and by our ties to Britain.

With the Empire of Britain at war, so too was Australia as part of the British Empire.

Yet in that moment of August 1914, Australia began her first steps out of the shadow of Empire and into the light of nationhood.

The Official Histories note that when the call to arms came, the response of Australians was ‘immediate’, ‘jubilant’, ‘unanimous’, ‘firm’ and ‘unequivocal’.

Historian Ernest Scott wrote that, ‘Thousands of young men offered themselves for training in the earliest contingents’.

He noted these Australians came from ‘every social strata’. And that there had never been ‘a more thoroughly democratic army’.

During the next four catastrophic years of the First World War, Australians and New Zealanders exemplified bravery in battle, mateship in mayhem, and endurance in extremis.

This spirit – the Anzac spirit – emerged in the tragedy of Gallipoli.

It permeated the trenches of the Western Front.

It was alive in the light horsemen who charged at Beersheba.

In war’s conflagration, Australians carved out a national character.

In war’s devastation, Australians discovered a national identity.

In war’s defeats and victories, Australians awakened a national consciousness.

Historian Charles Bean made the following observation:

‘… during four years in which nearly the whole world was so tested, the people in Australia looked on from afar…

They saw their own men – those who had dwelt in the same street or been daily travellers in the same railway trains – flash across the world’s consciousness like a shooting star…

Australians watched the name of their country rise high in the esteem of the world’s oldest and greatest nations.’

Bean wrote profoundly that ‘the Australian nation came to know itself.’

Just as the Anzac spirit shaped our national soul, our national soul sustained the Anzac spirit.

And since the First World War, it is a spirit which has characterised Australians whenever and wherever they have served and sacrificed.

Kokoda. Tobruk. The Coral Sea.

Kapyong. Long Tan. Dili.

Uruzgan. Al Muthanna. The Indo-Pacific.

On Anzac Day, we acknowledge the deeds of all Australians who have served in wars, conflicts and peacekeeping operations throughout our history.

On this sacred day, we honour the memories of the more than 103,000 Australians who made the ultimate sacrifice.

We remember them so we don’t forget who we are:

A people who choose courage over cowardice, camaraderie over tribalism, endeavour over indolence, gratitude over resentment, and national pride over national aversion.

The Anzac spirit helped us to prevail in war and prosper in peace.

In these difficult times, let us know ourselves again.

Lest we forget.
