Hardwood Fence Posts — Buying Guide

Why Choose Hardwood Fence Posts?

Australian hardwood fence posts are prized for their natural durability, strength and resistance to rot and termites. Quality hardwood species used in fencing — such as ironbark, red gum, spotted gum and grey box — have been used in Australian rural and garden fencing for generations. Their natural oils and dense timber structure provide excellent resistance to decay, making them highly competitive with treated pine in terms of service life, particularly in high-humidity and high-moisture environments.

Applications for Hardwood Fence Posts

  • Rural and farm strainer posts — hardwood is the traditional choice for end and corner strainer posts in Australian wire fencing; its strength and weight anchor the high tension loads of stretched wire mesh
  • Garden fencing posts — for timber paling fences, post-and-rail fencing and garden borders
  • Retaining wall construction — round hardwood posts for rustic retaining walls and garden edges
  • Timber post for horse fencing — where a heavy, stable post is required for gate hanging or high-pressure fence sections

Hardwood vs Treated Pine Posts

Both are widely used in Australian fencing. Hardwood provides superior natural durability without chemical treatment and has more character for decorative applications. Treated pine (H4 or H5 treated) offers consistent dimensions and lower upfront cost. For rural strainer posts where long in-ground life is required, hardwood is often preferred. For garden and residential applications, treated pine is the more economical choice.

Post Sizing Guide

Strainer posts for wire fencing should be a minimum of 125mm top diameter for residential wire mesh, increasing to 150mm or more for heavily tensioned rural wire fencing. Round hardwood posts are sold by length and minimum top diameter — refer to product listings for available sizes. Standard fence post lengths range from 1800mm to 3000mm.

Frequently Asked Questions

Do hardwood posts need to be treated?
Dense hardwood species such as ironbark and red gum do not require chemical treatment for their natural durability. Lesser-density hardwood species may benefit from treatment for extended in-ground life.

How long do hardwood fence posts last in the ground?
Quality hardwood species such as ironbark or red gum can last 30–50 years or more in the ground in many Australian soil conditions.
