Answering the question: yes and no.
Yes, because everyone in the world has been affected by this to a greater or lesser degree (unless they live under a rock); some by having family members or themselves affected, or some just by, well, you can't go on holidays internationally at the moment. And everywhere in between.
No, because some people are being selfish. Some don't seem to care. Also, places like Victoria, it's a disaster waiting to happen. (What's the chance schools will be shut down again for us poor kids?) Others, they have no cases and the only way it affects them is they can't travel outside their country. We're not 'all in this together'. Some people don't care about it. We're affected to different levels. Some people have to carry the weight of leadership, while others can just coast and follow the guidelines. We're not a united country, not really, so maybe they shouldn't try saying we are.
All the same, I understand what they're trying to say.
