This is from Nowra again. Part of the rocky ground by the beach at low tide apparently acted as a sort of trap to collect heavier objects after the tide went out, leading to this cache of shells.
Whenever I'm out shooting on location (as opposed to in studio) I try to think about how someone who just rocked up with a smartphone would take a photo in this particular spot, and then try to do something completely different from that. That approach often tends to lead to a much lower angle when capturing photos, which is what happened here.
