Talk about epic from Bungendore!! I like Mt Coree but there is no way I would drive from Bungendore to get there. Also, who says you need a pad to go bouldering?? You just have to use your head more and there are plenty of low ball boulders you could step off if it all gets too much. If I had the choice between a 20-30 min drive to some of the most pleasant granite bouldering in Australia and a 2 hour drive followed by a 20 minute uphill walk to climb the only 6 routes worth it on Wind Wall and around the corner at Mt Coree then I would opt for the former. Don't know about the comment that there are ~5 years left in the bolts at Corree. Going by ACT bolting standards those guys still have the price tags on them in comparison to most other areas.
Another area worth considering closer to Bungendore is Nerriga. Vulture wall etc are worth a look.
