– ~ 50% was used as fuel wood
• In 2008, international trade in wood products was worth about US
$620b

Value of imported wood products
• Australia imports around $4.2b of timber and paper
products annually, mainly:
– Paper & paperboard, manufactured paper products, sawn timber,
panel, wood pulp
• Importing countries include:

While the value of imported pulp decreased from $180 million to $164 million in
2011–12, the volume increased from 233 000 tonnes in 2010–11 to 256 000 tonnes in
2011–12 However, over the past five years the volume of pulp imports has declined by
about 29 per cent, partly reflecting closure of some paper mills in Australia that were
using imported pulp
The total volume of sawnwood imports fell by 6.5 per cent in 2011–12 to 791 000 tonnes
and the value of these imports was lower by 5.3 per cent to $448 million The fall in the
volume of total sawnwood imports reflects a fall in softwood sawnwood imports from
several European countries; imports from Austria, Estonia and Germany combined fell
by 38 per cent in 2011–12 Partly offsetting the aggregate fall in sawnwood imports,
imports from New Zealand (historically Australia’s major softwood sawnwood import
Chile also increased slightly
The volume of sawnwood imports from Austria, Estonia and Germany continued to
decline in the September and December quarters of 2012 relative to the same period
decline of sawnwood imports from Europe
The decline in sawnwood imports from European countries partly reflects European
sawnwood producers redirecting exports from Australia to the United States,
which has experienced an increase in housing activity over the past year Australian
sawnwood imports from the United States increased significantly between the
September quarter 2011 to the September quarter 2012 However Australian
sawnwood imports from the United States fell by almost half from the September
quarter 2012 to 9700 cubic metres in the December quarter 2012 (Figure 9)
The value of imports of miscellaneous forest products increased by 8.6 per cent to
$741 million and the value of imports of wood-based panels increased by 12 per cent
to $323 million in 2011–12 The volume and value of wood-based panel imports were
the highest recorded since 2000–01

Native hardwood logs are mainly harvested from public multi-use forests Less
than 1% of these forests is harvested annually Generally, all are regenerated
as native forests

Tree breakdown
• After harvest, the tree is broken down into a
hierarchy of log types, governed by value and product group
• Solid wood processing can only convert a portion of tree to the most valuable elements
• The remainder is channeled into other, product streams

Native forests
• These forests have regrown naturally or been resewn
after a major disturbance, such as a fire or harvest

Recycled timber supply
• As the demolition of older structures limits the resource, recycled timber supply is naturally restricted

Wood recovery
• Wood residues can be
recovered from processing,
building and deconstruction
• About 35% of the potential
resource,~0.5 million tonne,
is currently recovered and
reused for mulches, fuel or
remanufacture
• Transport costs strongly
influence potential reuse

Timber supply over time
• Wood supply is fundamentally
different to the supply of most other building materials
• Supply is conditionally renewable
– Resource can be drawn from the same spot again and again
• At any specific time, timber supply is limited by the availability and maturity of the forest estate
– It is bound to actions and events during the past 20-100 years
– Production cannot be increased by simply ramping up processing capacity

Summary
• Apparent consumption of solid wood and panel
annum
• The building sector consumes about 85% of solid

• Australia produces about 87% of its consumption of
