I think you are correct - I was recently looking at landrover paintcodes and they indicated that it was the roofs that were painted limstone and the whiteish bodies were painted in other various shades of "white".

Have no evidence for it yet, but I think that the Australian paint codes were different to the UK ones. And the Series 3 UK paint colour names were different to the series 2a codes in Australia. (Where is Brian Hjelm when you need an expert from the era.)
In fact the Series 3 Limestone being the colour of most of the Stage 1s
This is a brochure from Hermann Vlothuizen in Holland.

Which confirms the limestone name - but there is no listing of sandstone.

Virtually the same as my LWB ute although mine's Bush Fire Brigade orangy/red.
Mine doesn't have the Land Rover grill badge however although it does have the "six" badge.
