The new results archive on the Orienteering Australia website is now available at
http://www.orienteering.asn.au/results/.
This page contains a full list of Australian Championship and National League results (as well as many other Australian events). There is also an international section which contains a full set of WOC results, and most JWOC and World Cup results since the mid- to late-90s.
All parts of the page will be a work in progress and I hope to add more to it over time. (In particular, if any North American readers have results available in electronic form for APOC 1990 or 2002, or know how they might be tracked down, I'd like to hear from you).
