As you may (or may not) be aware we put aside money each year towards rebolting. We have also received a number of donations towards rebolting. Currently we have several hundred dollars available for rebolting work or anchor renewal. If you are involved in rebolting work or know someone that is get them to contact us. The money will be used to supply equipment (bolts, hangers, glue etc) for rebolting projects.
Also the Sydney Rockclimbing Club have a rebolting fund. Information on it can be found here.
