The snippets describe First Falls as being on Fourth Creek, not First Creek, but this is a known local naming quirk — the falls are genuinely called "First Falls" and are located in Morialta Conservation Park, South Australia. The POI name matches clearly.

--- First Falls, also known as Morialta Falls, is the largest of three waterfalls along Fourth Creek in Morialta Conservation Park, South Australia.

It drops 30 metres down a sheer quartzite cliff in a fan formation, making it a striking feature of the park's rugged landscape.

The falls can be reached via a short, easy trail from the Morialta Falls Carpark at the end of Morialta Falls Road, with a return walking distance of approximately 1. 8 kilometres.

Multiple vantage points offer views of the falls, including the Eagles View Lookout, which provides an elevated perspective over the cascade and surrounding cliffs. Visitors can also descend to the base of the falls for a closer look.
