Box jellyfish sighting, 7 Mile Beach , New South Wales

I found a box jellyfish washed up on the beach at Seven Mile Beach, Lennox Head, New South Wales, Australia. I noticed it yesterday searching for shells with my family, and didn't think much about it until I saw on the news one had been captured in Queensland. I am quite familiar with sea life common to my area, having done subjects in zoology in University and am very confident of the species. Just wanted to register this post to assist with records of sightings
