I'm not sure what's happening in Australia, but from what I've seen, the American media has been surprisingly good about it - Coverage about the memorials and some reflecting, then moving on. And really, I think that's quite appropriate... one day to briefly reflect on the physical and symbolic losses, reflect on the heroes of the day, then to move along as normal. Dwelling on something is never a good idea, but keeping it in mind is.
Also, as a semi-related side-note:
Especially around here, you often hear that people outside of New York and outside of families/friends of those who were killed aren't really affected emotionally by the attacks (government actions that spawned from the attacks aside). However, I know that personally it means a lot to me - I stood in one of the Twin Towers less than 2 months before the attacks. I remember that feeling of b being in something so great, so powerful, so much of an accomplishment to build. Many people consider the Twin Towers to have been symbols, because they were huge buildings where parts of the world came together for business. I see them as that, but also as one of the greatest examples of the greatest thing of man - Our ability to use our brains to do great things. One man with his crew had a vision of these gigantic buildings... architectural masterpieces... and successfully built them, using knowledge that he acquired over the years to create, and to make the world a better place. The attacks on the towers not only killed people, but it destroyed something that was built out of love, hard work, passion, and with our most valuable tool, the brain. Those terrorists not only attacked people, but the very basic foundations of what makes mankind so great.
