Can you please identify this little fellow for me, from my garden in the Adelaide Hills?

Martyn Robinson says

This is another flower spider, a Cetratus rubropunctatus, and it usually has red flecks on the tip of the abdomen. This species prefers to hunt on the green leaves and stems, but feeds in a similar way to other flower spiders, by a quick embrace with those long front legs, followed by a fast-acting paralysing bite. It’s a lovely-looking spider that’s harmless to humans.
