Sorry about the delay in updates. I've been living out of the country for most of the last 2 years so having the resources to put something decent together has been difficult. I collected a lot of additions and revisions on a recent trip back to the gramps in April/May. They should all be compiled and uploaded to the website some time in September when i get back to Australia.
www.grampiansbouldering.com is still the best place to send any information on new areas, problems, or corrections. If you contact me through there we can organize to get any topos or photos from you.
The best way to see that Halls Gap and the Vic Ranges are included into the next edition of the guide is to get out there and develop, develop, develop. For a new area to be worthy of inclusion it must contain a good standard of quality and quantity. I have no doubt that it exists, but at the time of writing it was poorly developed. In recent years there have only been a handful of climbers who have dedicated time to exploring, finding and developing new areas. It can be a very time consuming but rewarding task however it is completely necessary if the sport is to be pushed forwards.
