For those that are interested here is part of the conversation I had with the museum about what the timbers are. Quote
From this, I can tell you that the types of wood used in our Chrysler are:
Coachwood - Ceratopetalum apetalum (OR North Queensland Coachwood - Ceratopetalum succirubrum)
Queensland maple - Flindersia brayleyana
Pacific maple - Aglaia spectabilis OR Aglaia cucullata
Cudgerie - Hernandia bivalvis (OR Brown Cudgerie - Canarium australasicum). I also found it called Flindersia schottiana and Sloanea australis (via e.g. https://www.collinsdictionary.com/dictionary/english/cudgerie)
Southland beech - NOT FOUND but possibly also known as Silver beech - Nothofagus menziesii (via https://www.lexico.com/definition/southland_beech)
Alpine ash - Eucalyptus delegatensis
Japanese beech - Fagus crenata (via http://www.tree-guide.com/japanese-beech)
Oregon - could refer to Oregon ash (Fraxinus latifolia), Oregon cedar (Chamaecyparis lawsoniana), Oregon pine (Pseudotsuga menziesii)
I will note that these scientific names are not fixed, but can change over time as our understanding of taxonomy evolves.
I hope that information and the resources linked will be of assistance to you.

Just one other thing to note is Cudgerie is sometimes referred to as teak.
Anyway thought this info may interest some.
