Here's what I reckon and if you can't cop a bit of criticism make your page better!
Private Aussie Pages
Australian Crags, Canyons and Caves: Similar to this page. Route descriptions and photos, mainly Sydney and the Blue Mountains, but also Pt Perpendicular, Arapiles etc Dafd's Climbing Page: Similar to this page, fewer pics but covers the ACT and Buffalo. Crag X, Rod's Home Page: Coverage of a so-so new crag in the Blue Mountains. David Noble's Homepage: A good page - Blue Mountains Outdoors activities including climbing. The Original Queensland Climbing Reference: One of the best Aussie pages - quick loading, updated regularly, good trip reports and home of the excellent online e-zine Qurank. Go! Queensland Bouldering: Like the name suggests. Neil's Haul Bag: Worth checking out occasionally to see what he's up to! Especially the up-to-date info/guidebooks on his new routes and new crags. Tasmanian Climbing: Very professional, but can be a bit slow uploading. A great reference for Tasmanian climbing. Sydney Bouldering: Good, but not updated in years. Arapiles.com: An online forum of Aussie climbing. Well worth a look. AustralianBouldering.com: Another online forum, dedicated to bouldering Australia-wide. Excellent site for all bouldering devotees.
On-Line Climbing Guides
Sydney Guide: An incredibly comprehensive guidebook to the wider Sydney region. Highly recommended! theCrag: Another recommended, and very widely resourced site. Over 24,000 routes, but no beta. Rockclimbing at Wollongong: Quite comprehensive and a needed resource for a good, though often overlooked area. All the typos are a bit irritating though.
Climbing Australia. Mark Baker's site, not totally commercial but associated with Australian Sport CLimbing Federation. Lots of competition results, plus some superficial guides to crags around Australia.
