Hello I been to the rocks myself quite a few times and no matter how many times I go up there I always go and speak the MARINE RESCUE and get a run down from them , Also go down and have a look at the bar when its low tide running out and coming in that's the worst when that happens, Looking at the bar this way show you the worst parts, Yes web cam from RMS shows you but not whole bar only from the end of the bar to the ocean , But even on high tide it to can be bad due to swell , I myself only come back about 2 to 3 hours before and after the change of tide. I have had a few close calls there let me tell you, So SAFTEY FIRST. sometimes you can go out its ok then when you come back its different and it can scare you. So sit back and read the waves NO RUSH. There is 3 ways to go out 1, the big boat ramp from/to the big bar, 2 Back Creek which I don't think will suit you even Back creek there is a way you go out throw there ,AGAIN talk to MARINE RESCUE, 3 beach launch but you need a permit. And the most important LOG IN WITH MARINE RESCUE.
Also about 60meters before you head out the main / bar, This 60meters before the end of the bar is the worst when going in or out , This you don't see on the RMS website that's why you go have a look.
Good luck.
