This cache is situated where there has been a re-vegetation site planted. There are several sites like this around the national park to help maintain the integrity of the park. Fences have been put around to protect the vegetation from people and animals alike. Kangaroos still get in there though!
Please keep an eye out for reptiles at anytime, but especially during the warmer months and don't forget your park pass for entry. You are looking for a silver bison tube.
Happy caching and travel safely!
