Certain death or destruction ! This has gotta go ( nasty yellow dot

)
Midway through a jump today I looked down & noticed something in the water. Went back for a closer look & FFFFaaaaRRRkkkk

It was a jagged marker pole of some sort maybe 30cm accross that was only exposed in between waves.
It wasnt drifting either as i gave it a kick... it looked as if something had crashed into it, which would explain why it was just below the water line. I can see an accident waiting to happen - someone being ripped to shreds if they hit it / land on it or ripping the hull out of a yacht / pleasure craft.
I saw it at about 6:30pm which would make it a Fremantle tide height of .63 metres, a slightly higher tide & youd never no its there till you hit it

Does anyone know who to report this to & has anyone else seen it
Cheers
Ps If any of you GPS speeders see it - can you plot its exact location....
