HIGHCOM Facility Bravo-6, nicknamed the Hive, is a United Nations Space Command military base and its formal headquarters located in Sydney, Australia. The building was roughly conical in structure and on the outside it was surrounded in security gates and other defenses; while on the inside the entrance way bore an atrium.
Below the HIGHCOM Bravo-6 Facility is another massive facility. It is three kilometers below the surface and reinforced with massive blast plating, anti-EMP armor and three kilometers of solid rock. The UNSC Security Committee met here. One famous meeting was the debriefing of Lieutenant Wagner in front of the UNSC Security Committee on the Fall of Reach.
- The very old and famous painting "Washington Crossing the Delaware" was located here.
- Another painting by the name of "Admiral Cole's Last Stand" was located here.
- Its current status is unknown, because as stated in the first issue of Halo: Uprising, Australia is hinted at being the site of a UNSC-Covenant battle, although HIGHCOM may not have been the exact target.
