One has to wonder whose ass I have to chew out to fix a 70% margin right-aligned body paragraph. My parents would have no idea what is even on this page, but maybe that's part of the point.
Personally, I think it's fine for the NDS site itself to look design-focussed (or, like a Sephora catalog). I presume that slick, modern design won't be used on every government website.
Of the Australian government websites I've used, they seem to come in both extremes; some with incredibly poor UX/design, and others with some surprisingly great design. A similarly complex task on a bad site could take 60+ minutes, whereas on the well-designed site more like 5 minutes. Makes a big difference when trying to get things done.
All the glamour seems nice until you're in a country of continental expanse, with territories from the pacific islands to the caribbean, and with equal citizens living in areas with low-bandwidth internet access.
