The significance and meaning of Anzac Day has waxed and waned over the decades.

In the late-1960s and 1970s, many thought they were witnessing the demise of Anzac Day, as veterans of World War I passed away and Australia's military involvement in Vietnam was so contentious.

From the 1980s onwards it has revived, and has essentially become the country's de facto national day.

Now many recent migrants have fresh experiences of war, and yet their experiences aren't part of Anzac Day. 

Does the Anzac legend need an update to stay relevant?
