Explore Our Hardwood Posts & Fence Posts Range
Naturally Durable Australian Hardwood Posts
Both ranges draw on the same core strength of Australian hardwood: dense heartwood that delivers high load capacity, natural termite and decay resistance, and outstanding fixing hold — all without preservatives. The difference is the job. Hardwood Posts (Spotted Gum, ironbark) are chosen where strength meets appearance — dressed and oiled for verandah, deck, pergola and feature posts, or stress-graded for structural loads. Mixed Reds Fence Posts are a blended group of red-toned durable eucalypts — Red Ironbark, Red Mahogany, Grey Ironbark and related species — milled specifically for in-ground fencing. Durability class is the critical spec for any post, and it's set by AS 5604 (Timber — Natural Durability Ratings). Class 1 is the highest rating: 25+ years in ground contact and 40+ years above ground. Mixed Reds carry Class 1 in-ground durability, while the feature hardwoods deliver Class 1 above-ground looks and performance, with the most durable species suited to in-ground use too.

Installing and Maintaining Hardwood Posts & Fence Posts
Hardwood is dense, so pre-drill for all fixings and use hot-dipped galvanised or stainless steel fixings throughout — hardwood tannins accelerate corrosion of bare or zinc-plated steel, causing fastener failure and timber staining. For above-ground posts, fix to footings with galvanised or stainless stirrups to keep the base off the ground and dry. For in-ground posts, use a Class 1 durable species, compact granular backfill in layers, or for gate, corner and structural posts, dome the concrete collar at the surface to shed water away from the ground line where decay risk is highest. For load-bearing posts, size and fix in accordance with the relevant standards and a project engineer where required. To preserve the colour of dressed feature posts, finish with a quality exterior oil and re-apply periodically; left uncoated, durable hardwood weathers to a silver-grey while keeping its strength. Always seal cut ends, especially on weather-exposed or in-ground posts.

Durability class is the most important spec for a post, and it depends on placement. For above-ground posts — verandah, deck and pergola posts on stirrups — a Class 1 or 2 durable hardwood performs for decades. For in-ground posts the requirement is stricter: specify a Class 1 in-ground species such as ironbark or Mixed Reds, or an appropriately H4/H5-treated post if a less durable species is used, since constant ground contact is the most demanding exposure. Many dense post species are also BAL-29 capable, suiting bushfire-prone areas, but this depends on the species supplied — always confirm species and its durability and bushfire ratings against AS 5604 and AS 3959 for your application. Our team can advise on the right species and finish for above-ground or in-ground use.

JVS Timber sources hardwood and fence posts from certified producers and supplies product compliant with Australian industry standards. A naturally durable hardwood post that lasts decades without chemical treatment is an inherently sustainable choice, avoiding the waste of early replacement.
