Is located 2.8km south east of Birds Rock Trig, off Sunnyside Ridge within Newnes State Forest. The plan view is semi circular having a 120 degree arc, the arc being 90m and the diameter 50m.The elevation is more horseshoe in shape and having a height of about 80m. The rocky floor mostly devoid of any vegetation is raked at about 35 degrees. The entrance and a precarious ledge to access this huge overhang is a challenge. To date this is the largest cave documented on the whole of the Newnes Plateau, hence the name, so coined by Yuri Bolotin and Brian Fox on a bush walk, 28th November 2015.
