Well done!!! I’m really curious to find out what’s down that tunnel. Wouldn’t advise going back alone. I know that opal or gold mining was a hobby for many Australians, but mate, that’s quite the cave!!! Really odd...... I love seeing pics of the Australian bush. Andy is another one to post such eye candy. Thanks to both of you! I’ll ba back in Oz beginning 2020..... what a treat that will be!
