Fence post choice is very important

The timber species you choose should be class 1. or 2. in-ground durability (sometimes class 3. is ok if the post is substantial and is installed correctly in concrete to allow for drainage). if you cannot find seasoned timber you should use a stable species, or at least install it at the right time of year (in southern states, this is late Autumn).

Stable species with minimal shrinkage are kwila (class 2. i/g), native white cypress- laminated or solid(class 2. i/g) and cypress macrocarpa (class 3. i/g)

Less stable species like ironbark (class1. i/g) grey box (class1. i/g) spotted gum (class 2-3. i/g) blackbutt (class 2. i/g) should be installed in late Autumn. Any larger post than 150x150 becomes very unstable. Dense hardwoods dry slowly- a 200x200 post can take 6-8 years to season/ stabilize.

Acclimatizing coating in our harsh, dry climate are crucial. Cutek or Spescoat Deep treat are excellent for slowing down the drying process. Deep treat should not be used on laminated timbers.
