Jillbunya Rockhole 6 February 2007

Set off across the Nullarbor, on yet another grey cool day, and quickly got caught up with some road trains and road works – there is a major redevelopment of the highway (boy does it need it), and went on for kilometres. The land is now becoming flatter, with sparser vegetation. However, there are still clumps of small trees doted around the landscape. The road is also becomes straighter, with an initial stretch around Balladonia going for 130km and then 146kms of the straightest stretch of road in Australia heading east towards Caiguna. We watched carefully for the bend in the road at the end! We travelled through open country and found Caiguna Blowhole, which is a small sinkhole that opens into an enormous cave. The air rushes out through the hole due to convection and is very cool. The information at the site said the air flow can be up to 70kms! With a cool, strong wind blowing outside for the past two days the airflow was too cool! Stopped for diesel at Caiguna Roadhouse at $1.60/ litre and 30 cents more that down the road! Stopped at Jillbunya Rockhole for the night in very open countryside and watched as the wind became stronger and stronger all evening making lots of noise! Walked about the surrounding land before the wind came up but couldn’t find a Rockhole! Found a fully smashed and flattened light van from some past horrid accident which must have been someone’s nightmare!
