A enlarged 1m by 0.5m entrance at the foot of an eucalyptus plantation draughts strongly. An excavated crawl leads after 4m to an enlarged but still tight squeeze. At Easter 2013 this crawl was found to have become filled up and needed much excavation for re-exploration. (A layer of mud was found over previous capping holes.) This may be due to drainage during rain from the plantation, and also animal action. After the squeeze turning right passes another squeeze then a junction. Left leads to a calcite choke with a dig on the left, while on the right an awkward climb is followed by an 8m (undescended) pitch connecting to the Espada streamway about 80m from the main upstream entrance of that cave.

(The length above should be incorporated into the length of Espada).
