When saying 'us' this person was referring to 'us', as in the defence, not Australians or a broader community.

Does this highlight a broader problem?

Yes, there is a recognised "problem" that younger generations might not treat Anzac Day with the reverence that older generations do.
It's supposed to be a commemoration, a public display of respectful and thoughtful remembrance of the sacrifices that citizens of the colonies of the British Empire made when they answered the call to fight other Empires and later battles that Australia participated in.

The "elites" probably wondering how they can keep the day relevant to future generations in the absence of war on our soil.

Then again these days a World War would be much different to the other ones we've had.
Presumably a lot more remote controlled killing rather than hand to hand.
