I've already presented few times Sissy Crag as the best bouldering crag in Sydney. There are so many super classic problems. This time I present you Vitamin C - 7a. This is a very cool problem. The direct is call Foam - 6c, and goes straight up. Vitamin C takes the same start and then goes on the right with a nasty pinch you have to match, and before the dyno to a slopy sloper. Used to be pretty hard for me to get the last big move. Since that I figured out that I can bring up my right foot and then the dyno becomes much closer and easier to me.
