What is this path thingy extending from Australian coast?

Not sure what phenomenon gives rise to this pattern.
I have some ideas but don't want to lead your answers.  Thanks in advance.

I would have to say, its an exposed part of the island.

Such as this 






Exposed Part of the Island.kmz (809 B)

Thanks, yes i've explored the surrounding coastline pretty thoroughly.  Seems likely, I just wonder why this one has a bare or hollow center.  Differential erosion?  Another thing i thought is that it might be the petrified edges of a river (or a former river in some sense), since there are rivers nearby.

The rocks are in fact sedimentary , and hard ones because the sediments  came from igneous rocks up  on the hills. (much like Uluru/Ayres Rock is of a harder sedimentary rock than regular sandstone, so it remained uneroded.) 



Info from geoology of Weipa area...  the rocks at the  shoreline outcrops are hard peaks of  the Rolling Downs  Group . The Rolling Downs Group is very large  (over to  coasts of WA, SA !) and very flat. 
It was created by sedimentatio  and marine life.

Probably the parallel formation is due to some sort of uplift there, creating a fold. Its  (near)  the top of the ridge that divides the two river catchments.
The top of the fold  being weakened by cracking and being eroded away by the seas waves.


But the parallel lines may  possibly  be the result of some waterway acting like a mould, as in the sediments or lifeform lines the waterway, and then became a hard rock.
