South
Australia
Land which is
remote from
and undisturbed
by the presence
and influences
of settled
people.
Wilderness quality
was scaled
according to four
indicators:
remoteness from
settlement,
remoteness from
access, aesthetic
primitiveness and
biophysical
primitiveness;
wilderness quality
was then expressed
as classes: very
high, high or
moderately high.
Additative and
weighted additative
procedures ranked
sites according to
their wilderness
value; high-quality
wilderness could
then be
distinguished.
No special
consideration.
High-grade roads
were regarded as
access points
while low-grade
roads were
treated as
aesthetic
disturbances;
wilderness
quality relates to
the density of
linear structures
(such as
roadworks) per
unit area, Four-
wheel drive
transport was
seen as an
appropriate
wilderness travel
mode in arid and
semi-arid areas,

Tasmania
Largely free
of evidence of
human
artifacts,
activity and
disturbance;
remote from
substantial
human
artifacts and
areas where
there is
substantial
human activity
or disturbance,
and remote of
access.
Land whose
direct remoteness
(the map distance
between that
point and the
nearest intrusion)
and access
remoteness (the
minimum time
separation
between that
point and any
access point) are
d and t
respectively, for
a suitable choice
of values d (km)
and t (hours and
days).
Regular use of
mechanised
vehicles is
regarded as a
major intrusion;
and no special
provision was
made for the use
of coastal areas
by mechanised
vehicles as it was
assumed that use
was still low due
to the relative
inaccessibility.
The following
were regarded as
major intrusions:
all roads and all
vehicular tracks
accessible to and
frequently used by
off-road vehicles;
and all areas
where mechanised
transport is
intensively used or
where the use of
such transport has
led or is likely to
lead to the
formation of
permanent tracks
or cause long-term
environmental
disturbance.
