A lot of animals seem to have a slash of color(s) or shading going through the eye.
Then there are warning colors that serve a function in many animals. Bees, wasps, poison dart frogs, butterflies, and mimics of those.

That doesn't seem that large. Less than an inch in length and less than half that in width. That is more coin-sized than I would have guessed.
I'm sure the color pattern helps break up it's pattern compared to the background. Several factors could play into it. It might be truly rare. Host plant information would help to determine range. Seasonality of it's appearance. How long the adult stage lasts. How long the emergence of adults lasts. Probably a lot of other factors that I haven't thought of, but having some impact on rarity.
One source says it is common around Sydney.

Sometimes, sight image and just learning they are there will help. Suddenly, you may find them all over. I've had that happen.
The article says read time 2 minutes. I did it in about 20 seconds. Am I good or did they lie?
Yes.
It is a nice color and patterning. I imagine it is more useful against a different background. I wonder if it makes it more difficult to follow when moving. Longitudinal stripes on snakes seem to do that. Make them look longer and you focus on the stripes and they can more easily evade further interest.
They haven't had time to evolve a pattern for the bricks on my garage wall yet but I imagine it would work in a poorly lit cave.
They need a bottleneck and for some weird behavior to spontaneously develop for no reason. Or perhaps some other delusional reason that doesn't make any sense.
You're onto something, every time I saw it, it was sideways. I've bred sideways geckos!
South going or north going? And if it keeps on with that tail, it will have two heads. One behaving differently than the other due to unconsciousness.

Blue is a rare color for animal life. I think that birds and butterflies have to cheat.
What about fish?

This article explains how at least birds and butterflies are not "blue". They do not have blue pigment. Their feathers and scales evolved in such a way that they look blue because of the way that their feathers and scales interfere with light. But they do not have any blue pigment:

And even better it is written in Australian.
Why is the colour blue so rare in nature?

(Not) Blue-faced Honeyeater. I get the feathers on the fairywren because they do change colour depending on the light but it's bare skin on the honeyeater.

The bird is being very tricky. The black parts are black. But white parts are white, but the blue parts are that color by just reflecting blue light by using very precise gaps in strands of its feathers and not by using pigments.
Worse than that, they do not fool just humans:
How Birds Make Colorful Feathers | Bird Academy • The Cornell Lab
As one might expect from the amazing diversity of colors and patterns exhibited by more than 10,000 bird species found in the world, birds can see color. The colors in the feathers of a bird are formed in two different ways, from either pigments or from light refraction caused by the structure o ...
