I don't think it's Thomisus spectabilis because (through the use of external sources) their abdomen isn't rounded like this one, instead having two lumps on either side which seem quite prominent. Here are some photos: http://www.arachne.org.au/01_cms/details.asp?ID=1031
On the other hand, Zygometis xanthogaster seems to fit in with this individual: a little bit of orange hairs on the face, fully rounded abdomen with a distinct dark spot in the upper middle and light smaller ones neatly arranged towards the middle and back.

While on this topic, I feel some of the sightings under Thomisus spectabilis have been incorrectly identified: at a quick glance, they look like Zygometis zanthogaster.

Yumi - happy for you to take the lead but this reference states that Zygometris xanthogaster has brown stripes on its head.

Of the sightings submitted only that of Cath has the brown stripes

Sorry, I based my decision on the images from ALA: some of them look exactly like this one! Does that mean these are still Thomiscus spectabilis though? All the images from external sources that I can find have the lifted segments on both sides of the abdomen and isn't fully rounded while this and the other few sightings are.

Ok. And also, is the brown striping on the head a 'must'? Some individuals on ALA for example seem to have lighter stripes so maybe not having any stripes is a possibility? Like it might be that immatures haven't developed the stripes??

ALA is a bit of buyer beware in its sightings and use of photos so perhaps not a good source to base an ID on
