im pretty sure "toon" is australian red cedar or toona ciliata var. australias.
It is one of Australia's few native
deciduous trees. The timber is red in colour, easy to work and very highly valued. It was used extensively for furniture, wood panelling and construction, including shipbuilding, and was referred to as "Red Gold" by Australian settlers.
[5] Heavily and unsustainably exploited in the 19th Century and early 20th Century, almost all the large trees have been cut out and the species is essentially commercially extinct.
[6] However, the timber is relatively fast growing and following on from a wave of tree cutting in the 1950s, regrowth and timber from forestry sources currently provides trees up to 1 metre in diameter for the furniture trade in Australia and timber is not difficult to source.
