I was out there Sunday too, with the forcast supposedly 2.6m swell I was planning to fish for squid.
Instead I peered out at the heads and accidentally ended up at the peak.
I think the weatherman had the forcast backwards!
Botany is hard for squid, I never do well there - here's where I go though.
1 - Back the boat right up close to the rocks. burley hard and you'll be plagued with yakkas.
2 - Pull in next to the walkway and drift out to the middle, its deep here but it holds some squid.
3 - Between 4 and 6m of water through here, drift along and you'll cover some large weedy areas - you can go a bit further around the rocky areas to the east too. Just be careful of the rocks.
I've heard of people doing well to the east of #3, other side of the oil wharf. Never tried there though.
