A timber species guide for Australian furniture makers
Notes on the eucalypts and a few imports a small Australian furniture maker is most likely to use, with sourcing context for buyers working in board-foot quantities rather than container loads.
Tasmanian oak
Tasmanian oak is the trade name for three closely related eucalypts: messmate, alpine ash and mountain ash. It is the most widely available solid hardwood in Australian retail joinery, sits in the medium density range around 650 kilograms per cubic metre, and machines cleanly. The colour runs pale straw to a soft pinkish brown, and it stains evenly with a sealer coat. For a small studio building tables, side cabinets and shelving, it is the easiest hardwood to work with that still earns the name.
Queensland walnut
Queensland walnut is not a true walnut at all. It is Endiandra palmerstonii, a wet-tropics rainforest species that produces a dark, interlocked grain pattern with a subtle gold flash under finish. It is expensive, harder to find since the more aggressive logging restrictions of the 1990s, and prone to tear-out under hand planes because of the interlock. For show pieces it is unmatched; for production work the behaviour against tooling makes it a slow timber to run.
Blackbutt
Blackbutt is a workhorse eucalypt out of NSW and southern Queensland. Pale gold to a light brown, slightly straighter grained than Tasmanian oak, very hard wearing. It sits around 900 kilograms per cubic metre which puts it well above the medium density bracket. Blackbutt is the default choice for Australian flooring because it survives the foot traffic, but it is also a strong candidate for tabletops and bench seats where wear matters more than figure.
Spotted gum
Spotted gum is the timber that looks unmistakably Australian. The colour is a warm caramel through to a chocolate brown, the grain often runs in a wavy pattern that produces a quiet shimmer when oiled, and the density sits in the same range as blackbutt. It is the timber of choice for outdoor decking and pergolas because of the natural durability, but in furniture work it earns its keep on bench tops and bar surfaces where the figure carries the piece.
Jarrah
Jarrah is the West Australian eucalypt that built much of Perth's older housing stock. Deep red to a near-purple brown, very dense, very hard, and quite slow to dry properly. Reclaimed jarrah, recovered from demolition, is widely available and cheaper than freshly milled stock, and it is a sensible default for a maker who wants the colour without the kiln wait. Watch for nail and bolt damage in reclaimed boards; metal detector before you run anything across a planer.
Where the wallet line fits
None of the timbers above ended up in the Madera wallet line. We used American White Oak, Black Walnut and Black Cherry instead, for reasons covered in the sourcing journal entry. The short version is: at the billet sizes we needed, the American supply was more consistent and the cut-offs from larger US furniture mills were already a known feedstock. For furniture work at any scale above a small wallet, the eucalypts above will almost always make more sense.
Buying in board-foot quantities
For a small Australian studio buying timber in board-foot quantities rather than full pack, the most useful relationship to develop is with a local mill that takes mixed orders. Mathews Timber in Melbourne, Trend Timbers north of Sydney, and a handful of regional Queensland mills will sell single boards out of pack with a minimum order. That access is worth more than a bulk discount when a piece needs a particular figure or a particular colour match.
