The temperature peaked at 31.8 C (according to the Robertson Bush Fire Brigade's Weather Station). I know it has been much hotter elsewhere - but frankly, that's why I chose to live in Robertson.
We did take the opportunity to walk along the "far end" of the East Rim Walk at Fitzroy Falls.

The brownish patch of vegetation
shows where Eucalypts
are growing on a drier section
of the valley slope.

Looking into the Rainforest Gully
(below the drier sandstone plateau)
The trees are Coachwood, Sassafras, Pencil Cedars
and some Cabbage Tree Palms

The only Orchid photographing today.
It had a lovely bright colour,
which was refreshing.
There were a few dried up specimens
of Little Tongue Orchids
which I declined to photograph.
But the Butterflies were rejoicing in the heat. Below Burrawang (beside the Illawarra Highway) there is a patch of Purple Top (a weedy Verbena) which the Cabbage White Butterflies absolutely love to hang out on.

|The field below these Purple Tops|
is planted with
"Leafy Turnips" which are a summer
fodder crop for Dairy Cattle.
The connection with the Butterflies is shown in the two names:
Brassica rapa (Linnaeus) is the name of the Turnip.
Pieris rapae (Linnaeus, 1758) - the Cabbage White Butterfly).
The vegetable and the insect were both named by Linnaeus. More importantly they both share the specific name because one is the "Food Plant" of the other.
The adult butterflies are attracted to the flowers of the Purple Tops, but they lay their eggs in the Turnip crop just below the fence, as Turnips are related to Cabbages, and they provide the necessary food for the Caterpillars of these Butterflies.
