ISS Inc. is a member of the Australian Speleological Federation Inc  

Speleology is the exploration, description and scientific study of caves. 

ISS is based in Wollongong but has members in Canberra, Newcastle and Musswellbrook, Braidwood, Sydney and Tumut. ISS currently has approximately 20 members ranging in age from 6 weeks to over 80 years (but who’s counting?).

ISS is fortunate to have members from the earlier decades as active members who share their stories of caving, camping and exploration.
