I went down there today after going to St Kilda earlier on, the race boats were setting up.Still accessible a while back, there looks to be an old fence you can just walk around, then the track is easy to walk down.
We found a couple of maybe 3m x 4m spots to launch from, surrounded by 3m mangroves, though staying reasonably high had no probs with signal.
Need a launch pad or sorts to avoid dampness / rocks etc, though there are flat spots you can find.
I avoided RTH (and usually do anyway).
I thought about doing it from a kayak (hand launch / retrieve), but think it's safer (for the drone) just flying it from the elevated spot I found.
If I was game enough to do that I'd probably use the Spark, even though I'd hate to lose that too !
It'd still be cool to film those wrecks from a kayak, maybe combine footage from my Pocket along with some aerial footage.
We've just always hired them, last time was a while back $45 a day, probably a bit more now.
Should do a trip sometime, outgoing tide is really neat as the water swirling around the Santiago creates some great visuals, and then a walk on the Dorothy H Stirling is good to do on the low . . . even down to the barges and then hopefully incoming tide has turned for the run back (we put in at the boat ramp North Arm usually).
I chatted to old mate the safety dude when he was out on the bridge and he said ok to go in but to be careful with the drone and not fly it from there. From the bridge, the Santiago is a fair way out, I only got 2 short sub 1 minute flights due to the rain, nearly got the drone drenched both times, haha, gotta remember it's not weather sealed like my dslr's
