Finally, A Sydney Opera House Projection We Can All Be Proud Of

And that, ladies and gentlemen, is what we call an appropriate use of the Sydney Opera House sails.

The Invictus Games Opening Ceremony took place in Sydney on Saturday night and it was was a joy-filled, very Aussie-flavoured affair.

Some of the performances -- like Kate Ceberano and Ian Moss belting out the old Cold Chisel Classic "Flame Trees", or Magda Szubanski appearing as her Kath & Kim alter-ego Sharon -- might have been a bit lost on overseas visitors and athletes, but the ceremony had a fantastic feeling of goodwill.

Thousands of people braved some nasty Sydney storms which pushed the ceremony back an hour to enjoy the festivities, and to cheer on 500 athletes from 18 countries as they marched through the Opera House forecourt.

But the best moment? It had to be when images of athletes were projected on the famous white sails of the Opera House Yes, those same white sails that Prime Minister Scott Morrison had called "Sydney's biggest billboard" during the debate over The Everest horse race.

Here, at last, were uplifting images projected on the Opera House -- in a spirit of goodwill which could not have been further removed from the crass commercialism, bullying and partisanship which clouded the debate over The Everest.

No, you can't bet on discus throwers, sorry.

Prince Harry opened the Games, 45 years to the day after his grandmother the Queen opened the Opera House, and urged the crowd to give the competitors all the respect and support they deserve.

"It’s your job to cheer them on and share their stories.  It’s your responsibility to make sure your children know how amazing these guys and girls really are," he said.

Turning to the athletes, he said:

"You are the unconquered generation. You are the optimistic generation. You are the new generation of service and the role models to us all and you are going to put on one hell of a show over the next week."

That word "unconquered" was not accidental.

As we told you last week, The Invictus Games are so-named because the word "invictus" is Latin for "unconquered" -- a term which embodies the fighting spirit of wounded, injured and sick service personnel who compete in these games.

But for once, Harry was not the star of the show. Nor were any of the other performers or dignitaries. The real stars, of course, were the athletes, who will compete in 13 sports this week. They include 72 Australians.

And athletes from countries where our servicemen and women have served.

The Games run until October 27.
