Bullita Cave

[2] The cave has multiple entrances and is located underneath a field of limestone pavement which is over 30 kilometres (19 mi) in length.

[3][4] The cave contains a large number of holes which open up at the surface, revealing daylight, and some whole sections which are completely exposed, as well as fissures within its tunnels.

"[4] Operation Raleigh investigated the cave in an expedition in 1990; this was the first time that it was significantly explored.

[2] John Dunkley, an educator and caver who is currently a member of the Australian Speleological Federation, explored and observed the cave throughout the late 20th and early 21st century.

Even in these later studies, the exact number still varies between sources; the book Caves for the Uninitiated states that the known length of the cave in August 2011 was 120.4 kilometres (74.8 mi),[6] while John Dunkley's observations showed the cave as having a total length of more than 122 kilometres (76 mi)[3] and a journal article published in 2016 states that the cave is 123 kilometres (76 mi) in length.
