Yeah part of the difficulty in identifying is that it's quite dark on the outside to a depth of around 10mm and then light in the middle. You can see above on the side how the colour changes. I guess from water etc seeping in over the years. The house is from the 1930's, but I don't know if that stair well was original.
I picked up 4 <1m chunks of r3cycled house yesterday, 120 yo according to the yard guy. All 150mm or bigger wide by 100mm minimum depth. Tallow wood, blackbutt, tassie oak and spotted gum
