From major cities to regional towns and suburban centres in between, Australians have gathered to commemorate their veterans on Anzac Day

Tens of thousands attended dawn services and marches before the more-solemn activities gave way to traditional games of two-up at the pub.

While most of the morning's events were sombre and respectful, a handful were disrupted with interjections, booing and heckling.

At Melbourne's dawn service, a self-professed neo-Nazi was arrested after booing and calling out during a Welcome to Country from an Indigenous elder.

Prime Minister Anthony Albanese, who attended the dawn service at the Australian War Memorial in Canberra, said there was no place for those who disrupted the service.
