More than 100 people have been injured, after mighty waves crashed into them at the weekend.

Emergency services were called to the site on Saturday and three women were airlifted to hospital.

The site has gained popularity over the past year after visitors began posting photos of it on social media.

The accident at the weekend has induced calls for a lifeguard service to be posted at Figure 8 Pool and the NSW Parks and Wildlife Service has released the following advice for tourists:

Access to the pools is only possible at low tide, as the rock pools and area leading to them are under water at high tide.

Even at low tide, waves can crash across the pools.

Never turn your back on the ocean.

The rock platform surface is covered in slippery seaweed.

There are a few other deep rock pools in this location which you can swim or dip your feet in at low tide.

The return walk is challenging, so give yourself extra time.

There’s no lifeguard service at the pools.

There are no toilets or places selling food or water near the site.
