Pimpernel Rock is a deepwater pinnacle located off the coast of New South Wales. This advanced site features a complex topography of walls, caves, and reef structures that descend to 48 metres, with an average depth of 27 metres. The site is exposed to the East Australian Current, which can create strong, unpredictable conditions suitable for drift diving. Visibility ranges from 10 to 30 metres. Due to the significant depth and potential for powerful currents, this site requires careful decompression planning and is strictly for advanced divers. Boat access is mandatory, and divers should be prepared for shifting conditions throughout the 60-minute dive duration.
