Tasmanian Oak is a light-coloured hardwood that is easy to work with and produces a beautiful warm finish. Grown in Tasmania, Tasmanian Oak consists of the same species as Victorian ash – with the addition of Messmate. Tasmanian Oak has slightly more tonal depth and is renowned for its excellent staining qualities, making it easy to match with existing finishes.
What makes our Tasmanian Oak truly unique is how production improves its use and performance. Once our slabs are quarter sawn to ensure optimal stability, our timber is cut perfectly straight to give you a superior Tasmanian Oak.
As a strong and stable hardwood, Tasmanian Oak offers great workability due to its high sanding and gluing potential. Suitable for a range of uses, Tasmanian Oak is the perfect timber for interior applications like furniture and joinery, staircase components, DAR & sawn, flooring and lining.

Victorian ash and Tasmanian Oak have a number of similarities as both varieties are known to be durable, versatile and easy to work with. Victorian ash refers to a hardwood sourced from Victoria and made up of two species of timber – Eucalyptus Regnans and Eucalyptus Delegatensis. Tasmanian Oak includes these two species with the addition of Eucalyptus Obliqua (Messmate) and is sourced from Tasmania. Both varieties are considered light coloured hardwoods, however Victorian ash tends to have a lighter and more consistent finish, while Tasmanian Oak is found to have additional pink and brown tones.
Tasmanian Oak is a light-coloured hardwood that can vary from a straw blonde to a light brown finish with shades of pink and cream throughout. Tasmanian Oak can often have large variations in colour as the timber tends to darken as the tree grows.
Tasmanian Oak is a great timber to work with, it is easy to cut, sand, plane and glue. Even better, the light colour allows it to be stained any colour.
Tasmanian Oak is a versatile hardwood making it suitable for a range of uses such as construction and interior applications, this includes furniture and joinery, staircase components, DAR & sawn, flooring and lining.
