One of the most treacherous to get to rock fishing spots in Sydney, and possibly Australia. How do you get there? Thats up to you, but you will get to a section where the name will make sense. However, this way will likely kill you, so it is HIGHLY ADVISED to treat it like a lead climb or do an abseil.
The D5 rating is for the knowledge and skill of properly setting up you own safety gear, it is for reasearching the way down to the cache, it is for assessing the risks involved and sheer mentality to do this.
Once you are at the correct spot, you should see a large concrete square outlet of sorts. To the left of it you will see the cave in the below photo. Crawl in and retrieve your prize.
DO NOT ATTEMPT THIS AFTER ANY RAIN
