I was going to make a post about this since I'm an Aussie myself. Thanks for mentioning it.
It's a terrible situation that happened, even on one of the most gentle rides at the theme park. I think it's the biggest disaster any of our theme parks have had, at least in many many years.
Thoughts go out to all of the people affected by it, hopefully they can recover, and maybe one day find enjoyment at a theme park again.
