Nice images, John! I would say that this spider belongs to the genus Isopeda, as defined in the revision by Hirst 1990 (Records of South Aust Museum 24:11-26). The main feature justifying this is the 2-3 pairs of spots/short streaks on the abdomen. Holconia has large blackish patches in place of these spots. Difficult to say whether it is Isopeda vasta. The key defining feature of this species group is the presence of a comb of short, rod-like setae on trochanter I, and that is not clearly visible in these images. However, Hirst 1992 reports that I. vasta is a Queensland/Northern NSW species. This individual looks overall very much like I. montana, which I have seen in Wonboyn, but to be safe, I would place it as Isopeda sp.

Note that the genus Holconia is likely to be collapsed into genus Isopeda in the near future because of a recent DNA study (Agnarsson and Rayor 2013 "A molecular phylogeny of the Australian huntsman spiders: implications for taxonomy and social behaviour" Molecular Phylogenetics and Evolution 69: 895.) At the present time, it still remains as a valid taxon on ALA.
