Measured last year each of these a couple of times with a GPS
Slip to level with pontoon - 60m
Slip to turn point and back to slip - 5.2k
Slip to first wires crossing river - 1k
Slip to turn point - 2.57k
The slip to pontoon was level with the upsteam corner of slipway on straight road side, moving upsteam till level (on same side as straight road) with uppermost end of pontoon.
500m point is somewhere around the swimmers hut. The bush just past it I think. Need another one or two runs to make certain.
Dave I take it you mean the large house by the grotto? Also GPS or otherwise measured?
