But Anzac Day will be marked across the country in a way no one would have envisaged a few months ago, before the COVID-19 pandemic.

For first time since the Spanish flu hit in 1919, Anzac Day marches won't be held. And it will be the first time ever that no public ceremonies will take place.

Replacing the chilly dawn gathering of veterans and their families outside the Australian War Memorial in Canberra will be a national commemorative service off-limits to the public but broadcast by the ABC from 5.30am.

Prime Minister Scott Morrison will deliver the address and the broadcast will end with The Ode, The Last Post and a one-minute silence at 6am.

"This year, we will not be gathering at the local cenotaph, or attending gunfire breakfasts at the local RSL, or gathering together to bow our heads in silence and listen to the bugles at dawn," Mr Morrison says.

"But we will still remember the sacrifice of those who gave so much for us at Gallipoli and on many fronts, as we ourselves give what we can to protect Australian lives while we face this terrible virus."

Broadcast coverage of services in other cities will follow.

Serving men and women like Corporal Michael Linke, a loadmaster for No.37 Squadron at RAAF Richmond, are planning their own events.

"I suspect I'll be wearing uniform and doing a small ceremony with family in the alleyway behind my house," Corporal Linke said.

Someone who will get to attend a ceremony is RAAF Corporal Frank Borton, who has been selected for the catafalque party at Adelaide's service.

"On this Anzac Day, I will proudly reflect on my service and pause to acknowledge my fellow brothers and sisters' contributions to making us the united country that we are today."

The RSL's Light Up the Dawn campaign asks Australians to stand on their balcony or in their driveway or living room with a torch or candle immediately following the televised dawn service, and share tributes on social media.

An address by Governor-General David Hurley, a former defence force chief, will be broadcast at 6.55pm.

Director of the Australian War Memorial, Matt Anderson said the COVID-19 pandemic makes this year's Anzac Day all the more important.

"We are resolute in our commitment to ensuring Australians can honour the Australian servicemen and servicewomen who have served in the past, and recognise those who are currently serving."

Not-for-profit support organisation Soldier On is organising a virtual Anzac Day commemoration service, also including an address by Governor-General Hurley.

Veterans Affairs Minister Darren Chester says Australia is facing the most significant challenge and threat to their way of life since World War II.

"Whether it's a solitary driveway tribute, baking Anzac biscuits, a small ceremony with your household, sharing a message for our service personnel, or watching the televised service ... I encourage everyone to pause, reflect and say a simple 'thank you for your service'."
