Great shots PIO! What is the purpose of the filter?
As an Aussie, I'm a little ashamed to admit that I never knew that Australia Day was such a recent thingI remember celebrating it as a kid, but don't remember exactly when the celebrations started.
I always learn so much through your TRs!
Google is my friend.

I started enjoying the Melbourne festivals about *mumble mumble* years ago when I was at Melbourne Uni. That's about as far back as my memory banks go.

The filter? It acts like sunglasses. The 9-stop one is very dark and I really can't see through it at all. And like sunglasses, it will block out the light so that if I want to get a shot exposed so that we can see it, I get to play with the exposure parameters - ISO, aperture, shutter speed. In this case, I left my camera lens open for longer to achieve an image on the sensor. Some of the pictures in this set were taken with the shutter left open for between 35 - 45 seconds.
For the fireworks, I can get more firework trails in the shot without over-exposing the image. At least....that's the theory. I think that because it is filtering out the bright light, you can get the lovely fireworks colours shine through more on the image.
I've now got a baseline to work with now and will be adjusting ISO, aperture and/or time next time to see what the effect is.
In the case of Treasure Falls, I posted two similar images of Treasure Falls. For one of them, I used that filter and adjusted the settings to get the image. If you do head back to look, you may find that in one of them, the water 'flow' seems fuller and whiter; and it gives the impression of where the water moves more. For the type of photography that I do, that's the other practical use of the filter.
