Waddywood (Acacia peuce), Uses and Properties

Waddywood, also called acacia peuce, has the same 4,500 lbf Janka rating. The central part of Australia is home to this rare and endangered species.

Aboriginal people call a fight with sticks a “waddy,” and settlers and Aboriginal people use wood from waddy trees to make tools and weapons. The wood has been used for fence posts because it doesn’t attract termites.

Acacia peuce is a type of tree that grows only in central Australia. It is also called Birdsville wattle, waddy, waddi, or waddy-wood.

The single, pale yellow flowers are not very noticeable, and the pods are large (up to 5×20 cm), flat, and made of paper. They are large and flat (6–14 mm long, 4–8.5 mm wide). They are dull, dark brown to black, and don’t have arils, which would help them spread.

The tree grows in open, dry plains that get less than 150 millimeters (5.9 inches) of rain a year. They grow on shallow sand aprons over gibber or clay slopes and plains, between longitudinal dunes, or on alluvial flats between temporary waterways.

Pastoralists used the tree to make fenceposts and stockyards that were very strong and didn’t get eaten by termites. After being cut for posts, stumps grow back quickly.


The Acacia peuce, also called the Waddy-wood, Waddy, and waddi, is one of Australia’s rarest trees because it only grows in three places.

The Waddy-wood (Acacia peuce) is only found in Central Australia. It grows on the western and eastern margins of the Simpson Desert, at Andado Station in the Northern Territory (approximately 230 km southeast of Alice Springs), and in Queensland’s Birdsville and Boulia.

At Andado Station, the Waddy-wood is protected in the Acacia peuce-only Mac Clarke (Acacia peuce) Conservation Reserve, NT.


Neither the CITES Appendices nor the IUCN Red List of Threatened Species includes this particular wood species. On the other hand, Australia’s Environment Protection and Biodiversity Conservation Act lists it as a vulnerable species that needs to be protected.

Waddywood Hardness

Waddy wood is a hardwood that is highly sought after. This is because of how nice the wood grain looks and how well it stands up to wear and rot. It is 23% harder than oak, a highly sturdy wood.

Waddy Wood identification

The wood is very hard and dense, and the heartwood is a dark purple color. The trunk and branches have a grey-brown bark that is rough and fibrous.

Trees that are young and saplings have a coniferous habit and can take three years to reach a height of one meter (three feet) (3 ft). Some may live longer than 500 years.

Simple axillary inflorescences are held up by peduncles that are 12 to 15 mm (0.47 to 0.59 in) long.

The heads of the inflorescence are round and have 5 flowers each. The flowers, which are pale yellow, bloom in the spring and autumn, frequently after periods of heavy rain.

After flowering, this species makes long, flat pods that feel like paper and have large, flat seeds.

Color and appearance

The heartwood is dark reddish brown or purple-brown, and sometimes it looks almost black. The edges of the light yellow sapwood are very clear.

Straight grain and a homogeneous, medium-density texture can be found. It may be mistaken for gidgee (Acacia cambagei) or pink gidgee (A. crombiei) because it has a very dark purple heartwood, is very dense, and the heartwood glows. Most of the time, waddywood will have more parenchyma and slightly smaller pores.

Heartwood glows under a black light, and the bark of a waddywood tree is rough and grey-brown.


Simple axillary inflorescences are held up by peduncles that are 12 to 15 mm (0.47 to 0.59 in) long.

The heads of the inflorescence are round and have 5 flowers each. The flowers are pale yellow and usually bloom in the fall and spring after heavy rain.

Waddy wood Fruit/seeds

After flowering, this species makes long, flat pods that feel like paper and have large, flat seeds.

Rot resistance

Given its past use as fence posts, the wood is assumed to be durable.

Strength and Durability

With a Janka hardness of 4,630 lbf, the wood is hard to cut by hand or machine. But the finished product looks good and will last a long time. Even though carpenters don’t like it because it’s hard to work with, the customer will always be happy.

Allergies and toxicity

Aside from the health risks that come with wood dust in general, no other health problems have been linked to Waddywood (though this may be due to the rarity of the tree itself).


Due to their high density, it isn’t easy to work with hand or machine tools. Reportedly turns and finishes well.

Waddywood uses

Because Acacia peuce doesn’t rot, it’s used to make fence posts. It’s also popular for making turned objects and can be fun to carve and use for other small decorative items.

Aboriginal Australians use the tree’s wood to make waddi clubs, which is how the tree got its common name.

Waddywood Related Species

Raspberry jam (Acacia acuminata)

Acacia acuminata is a tree in the family Fabaceae. It is also called mangart and jam. It only lives in Western Australia and can be found all over the state’s southwest.

It can grow up to 10 meters tall in ideal conditions, but it grows no higher than 5 meters in most places. The wood is strong and hard, has a pretty red color, and has a tight grain.

It has been used a lot for fence posts, decorative items, and things that need to hold a lot of weight, like sheave blocks.

Mulga (Acacia aneura)

Acacia aneura is a common plant that grows in most types of inland Australian vegetation. The shape, height, and shape of the leaves and seed pods of mulga trees vary a lot. The IUCN Red List of Threatened Species says the plant is of “Least Concern” (2013).

Mulga has changed a lot to live in the Australian desert. It has thick-skinned phyllodes, like many Acacia species, so it loses less water. Mulga roots go deep into the soil to find deep water and help deal with soils that don’t have enough nutrients.

Brown salwood (Acacia aulacocarpa)

An Australian shrub or tree in the Fabaceae family is called Acacia aulacocarpa. It is also called New Guinea wattle or golden flowered salwood.

It lives in northern Australia, Papua New Guinea, Irian Jaya, and some parts of Indonesia. It has phyllodes instead of true leaves, like most Acacias.
