It is still accurate I jump there last Xmas. For the dates you will be out there expect rain and that makes the climb slippy so if you don't already climb, start because although possible with no experience you will feel a lot better if you know what you Can or cannot do. Finding the exit points is not easy but possible with the above article or get a local climbing chappy to show you.
The main wall is a great jump the rest other two easy ones to get to are pretty low and require a low tide. The rest need hard core climbing skills to get to or the payment of locals to rig some ropes that you can jumar up.
The place is epic just be carful on the climbing as it has the potential hurt/kill you on most of the approaches. Oh and if going up for a sunset jump take a torch it gets very dark very quickly and climbing down with no torch is not an option.
Stay safe
