Mr.Bruce
Imported timber packaging must comply to ISPM 15 international phytosanitary prevention convention.
It can be treated with either Methyl-bromide, or heat treated with the core reaching 65deg for 30 minutes.
Only certified sources of material and packaging suppliers are permitted to supply, the timber / product.
The finished crate and its components will be stamped,
If the product comes into Australia without this stamp and certification papers it will be quarantined and you will be up for de-vanning, unpacking, fumigation and destruction of packaging materials which may also include any soft furnishings.
In a previous life i managed a timber packaging business in Melbourne.

Forgot to add, plywoods and particle boards are exempt as by the nature of there manufacture they exceed the requirements and are there fore exempt.

Regards
Dave
