If walking from the small, fire trail parking area on Mount Macedon Rd (300m north of the C328/Memorial Cross turnoff), the "Melbourne Views" buttress that contains Space Jugging will be one of the first you reach, and is just past the quarry. Look for a large pile of rockfall reaching down to the base of the rocks, and walk up to the left of it to reach Melbourne View Buttress, which starts half way up the cliff.
Alternatively, from the summit access track, continue past the fenced lookout for about 75m, until just before the track ends and turns to a rocky scramble. Turn off to the right of the track and head NE for ~60m, tending right when you see the white gum tree (which grows from the base of the cliff, next to Gumslinger) to get to the access gully rather than the top of the cliff.
Space Jugging starts at the overhanging, juggy crack left of the left arete. Up and slightly right to a carrot bolt, then follow the jugs up the arete past another bolt.
