Cape Burney? Ie greenough river mouth. Suggest you pm Austin who has kited those southern outer reefs more than anyone that I know.
Definitely decent swell out there, but a long way out if you screw up.
Have you guys tried Horrocks? Similar swell but a lot closer in. It's a lagoon with a nice reef that gets deeper towards the north.
Your talking about the A frame that breaks to your right when standing from the look out.
I wouldn't say 1.5kms - probably half that.
Hit it up when the swells over 4m. Anything less is just a slow roller and the beachys or Hells is better.
needs a good swell to get going, 2m solid ground swell and 14 seconds, hells is good for 1.6m and up, get the conditions right and you'll know where the name comes from,
