This geocache was part of GC Project: It's Raining Caches 2025. The project's aim was to create a rain of new geocaches to fall from the sky across the state of NSW at 9am on 19th January 2025 - 1 week before Sydney Geoquest, the first Block Party in the Southern Hemisphere. Many legendary hiders came together to generously contribute their finest geocaches to build excitement and connection amongst the community and for all finders to enjoy years after the event.
This geocache helped make it rain.
