Jagungal weather stations lat and long

[Lophophaps]

I need the lat and long of two weather stations near Jagungal. I know where they are but cannot see a way to get the numbers accurately. This website
http://www.ga.gov.au/nmd/geodesy/datums ... to_geo.jsp
gives a way to convert, but I don't know which figures to submit.

The weather stations are:
On the Grey Mare FT, about 2 kilometres west of O'Keefes hut, at the start of the ascent to Jagungal.
On the Valentine FT, about 2 kilometres north of Schlink Hilton, at the Geehi Reservoir turnoff.

TIA.

Using Six maps and the coordinate tool and zooming in on the imagery to identify the structure I get

Grey Mare FT weather station Lat -36.135496 Lon 148.389498

Valentines FT weather station - Lat -36.259725 Lon 148.377365

From memory the location for this one is not quite correct on the topo maps but can be seen on the imagery when zoomed right in. The location is about 200m west of the topo map location. It is not visible from the Valentines ft but the ft extension (to the east) will take you to it. This may well have been moved a bit when they reduced to snow monitoring functions.

You can do the same with Google maps to identify the structures then click to get lat/lon.

Mark, thanks. My sextant and astrolabe don't give lat and long.
