The event area is located
close to Perth, the capital of Western Australia. In
spite of the close proximity (100 km) to Western
Australia's major city, the event area is largely
uncleared forest. The primary reason for this is the
arid climate experienced over much of Western
Australia. When Perth was first settled in 1829, access
to reliable water supplies was a problem for many
years. The damming of most of the rivers flowing
towards the coast between Perth and the south coast of
WA solved the water problem, and had an unexpected
side-effect of tying up large areas of land for use as
water catchment reserves. The large areas of forest to
the east and south east of Perth that are reserved for
water catchment purposes can be clearly seen on any
large scale map of the south west of WA. These areas
have been widely used by Western Australian rogainers
for many years, the close proximity of these areas to
Perth is one of the great things about rogaining in
Western Australia.
As Western Australia is
fairly flat
when compared with the rest of Australia and other
countries, our rogaining maps typically
use 5 m contours. Features on a WA rogaining map may be
defined by a single contour, this may prove a challenge
for interstate or overseas competitors who are used to 10 or 20
metre contours and events held in areas with large hills
or small mountains.
A feature of forested areas
in Western Australia is the large number of tracks,
which vary in size from minor roads to trail bike and
walking tracks. Some are in regular use and others are
in varying states of decay. Accurate mapping of these
tracks is generally impossible and all competitors are
warned about the unreliability of tracks when used for
navigation. This event area is an eroded lateritic
landscape, with remnant granite features such as
boulders and bare granite rock surfaces, along with
sandy or laterite (gravel) features. There is no
limestone or sandstone. There are small cliffs, up to several metres in height
which occur on granite
features on steep hillsides or more commonly on
“breakaways”, which are laterite ridges along spurs.
There are no deep rivers or swamps.
The data from which WARA
produces its maps nearly always over-maps water courses,
particularly in farming areas. In many cases the “blue line” on the map does
not translate to any recognisable feature on the
ground. Conversely, some water courses have been
heavily eroded over geological time into gullies, these
may be only a few metres across and up to several metres
deep. Because of their small size such gullies may not
show as distinct features on the competition map. In
general you should expect to be able to walk freely
throughout the competition area.
The vegetation in the event area is typical for
Australia and the area's rainfall. For international
visitors this means that virtually all plants will be
unfamiliar, as they are endemic to either Australia, or
Western Australia.
The trees are predominantly Eucalypts -
Jarrah, Marri and Wandoo being the main species and all
found only in WA.
Eucalypts are part of the Myrtle family and are the
dominant trees over much of Australia.
Jarrah is a tall
tree to 60m given suitable conditions, but in the event
area is much smaller at 5 - 10 metres. Jarrah is highly
prized for its timber, which is dark red in colour,
hard, and much used as a structural timber and for
making furniture.
Marri is also tall - up to 60 m given suitable
conditions, but again in the event area is much smaller
at 5 - 10 metres. Marri is known locally as red-gum,
and is also highly prized for its timber. Jarrah and
Marri occur either together or in pure stands, with
associated undergrowth, known generically as Jarrah
woodland. For rogainers this Jarrah woodland
under-storey usually comprises a variety of small to
medium shrubs (0.3 – 2m high) , that can occasionally
make walking difficult. Visibility depends on the
thickness of the forest, but is typically about 100 m.
Wandoo is the final species found commonly in the event
area. Wandoo is a white-barked tree that occurs over
wide areas of WA, generally in areas of lower rainfall.
In the event area the Wandoo is 5 – 10 metres in
height. Wandoo woodland is much loved by WA rogainers
because it tends to have little or no understorey,
thereby making it very easy to walk through, with good
visibility (up to several hundred metres).
Finally the event area also includes a variety of
smaller shrubs and bushes. Most of these are prickly,
some very so, again this is typical of Australian flora
adapted to arid conditions. WA
rogainers are very familiar with Parrot Bush (local
name). This species is endemic to WA and therefore
not
appreciated by other Australian rogainers, or
international visitors. The botanical name for Parrot
Bush was Dryandra Sessilis, however this has been
recently amended to Banksia Sessilis. Parrot bush is
1-3 m high, prickly, can form dense thickets (visibility
less than 5 metres) and is widespread over much of the
south west of WA. Sadly it occurs within the event area!
There are several other species related to Parrot Bush
with similar habit in the event area, most are at least
as prickly as Parrot Bush.
Forested areas in the south west of Western Australia
are subject to controlled burning at regular intervals,
to prevent an excessive build up of timber on the forest
floor and reduce the impact of
seasonal bush-fires, which can be very destructive given
unfavourable weather conditions and high fuel loads.
For rogainers the main impact is that areas that have
been recently burnt tend to be free of fallen timber and
the understorey tends to be non-existent. As time
progresses however the understorey recovers vigorously,
this is a characteristic of Australian forests. It can
mean that areas burnt several years ago can be quite
thick with undergrowth and harder to traverse.
Photographs
of the vegetation can be viewed here.
In most cases expect to be able to walk freely
throughout the competition area, with only minor
inconvenience from the local vegetation - the dreaded parrot bush!
While most of the event area is forested, the amount of
rainfall received is small when compared with wetter
climates in other countries. There are no permanent
watercourses of any size in the event area. It is
possible that you will see no water at all while
competing in the event, although this will depend on
seasonal rains prior to the event. Any water that you
do see should not be relied upon for consumption.
The fauna in the event area is typical for Australia and
the area's rainfall. Kangaroos (Western Grey) are
widespread, as are Emus. Western Grey Kangaroos are
large, about 1.3 m tall and weigh 30-60 kg. Emus are
large flightless birds, second only to the Ostrich in
size and are typically 1.5 m tall. You'll likely
see Kangaroos while competing and have a reasonable
chance of seeing Emus.
The event area is home to other smaller marsupials and
reptiles, but as they are mostly timid, nocturnal or
prefer warmer weather, you'll be unlikely to any. What
you will see though are numerous species of birds native
to these forests, especially the large noisy black cockatoo
which are impossible to miss. On
the farmland expect to see sheep and cattle - if there
are bulls we'll warn you!
6. What
facilities will be available at
the event site?
Information about the start/finish area will be detailed
on this site, as they are decided, but for now:
The main things for international competitors to note
are:
Transportation will be made available from Perth
City and Perth Airport to and from the competition
(Hash) site - "See
Information"
There are no accommodation facilities between
the edge of the Perth metropolitan area and the Hash
site. The nearest small country towns are Wandering
and Brookton.
Western Australia is a large place. Once you leave
the Perth metropolitan area you can travel many
kilometres without encountering any facilities such
as road houses, petrol stations and the like.
Mobile phone coverage in areas outside the Perth
metropolitan area should not be relied upon.
If you intend to drive from Perth (or elsewhere) to
and from the Hash site be aware that facilities are
scarce between the edge of the Perth metropolitan
area and the Hash site. You should plan to leave
Perth (or other built-up area) with a full tank
of fuel and be capable of changing a flat tyre.
Travelling at night to or from the Hash site is not
recommended. Part of the access to the Hash site is
along gravel (unsealed) roads where care is
required, these roads are more difficult to travel
at night. In addition the danger of collisions with
local wildlife, especially kangaroos, is much
greater at night. If you are hiring a vehicle you
may void your insurance by travelling on gravel
roads, check this with the hire company
At the Hash site there will be no facilities such as
water, power or showers, there are no permanent
structures (buildings) at or near the Hash site.
Portable toilets are provided.
You need to provide
your own camping equipment and food for use
before and after the event.
Water will be
available for International and Interstate
competitors. Food will be provided during the event
(all competitors). Food will also be provided on
the Friday night prior to the event - this needs to
be pre-ordered - "See Information"
7. What
snakes, spiders and other bugs should we be aware of?
Spiders - look scary, big
and hairy!! but mostly harmless
8. What
other navigational events
will be on in WA at that time?
The
WA Orienteering Association holds events on most
Sundays between March and September. On the weekend
before the Australian Championships is the OWA Autumn
Classic - a 2-day event held this year at Kenine Hill
south of Williams, about 2hours south of Perth.
The weekend after the
Rogaine on 14th June is a standard event at Darkin
River, an area off the Brookton Highway 30km east of
Roleystone.
Please send it through and
we'll add it here for others - even if you know the
answer but think new participants may need to know send
