Last official location was on the "dolphin" pylon in the middle of the river between Pelican Point & Point Majestic .. although its location may have changed .. it was more at risk from yacht booms constantly knocking it off, rather than vandals...

i know it used to be located on inner dolphin which is the white stick with a red square shape on top which marks the port side of a channel,when travelling upstream(lateral mark i think) at the end of peli pt
as far as i know there are only 2 named 'dolphin ' in this part of the river
but recently the rumor has the wind gauge over near majestics bank.
there is(or was recently) a gadget there with all sorts of instruments on it.
inner dolphin still has instruments on it as well. these occasionally got smashed by passing yachts.see the attached pic for aprox locations.

There is a green and white channel marker just off (NW of) Majestic Pt - on that sand bar in Snides picture (a few hundred metres west of Snides assumed location). There is a little windy-mill thingo and lots of cables and stuff there... Is this it???

i think magestic has now changed its name to agrestic... could be wrong though
