From photo notes it looks like "Boarders at Bramcourt (?) Katoomba"
There is a similarity to Jean Tompson, front row 2nd from the left and it was with the Baker family photos. It was probably taken in the early 1930s.
I think this photo is associated with the Winduss family but can't identify anyone for sure.
Possibly Albert Gleadow Winduss is standing at the left second row. From other family photos George Charles Winduss looks a little like the gentleman sitting behind the dog wearing a hat.
This photo was probably taken in the 1890s or early 1900s.
These photos belonged to Laurie Baker and are possibly of the Baker cousins.
