The non-fence control expenditure in the Esperance region is about 70% of
the Kalbarri to Lake Moore section yet it provides less than a tenth of the
protection against emus and possibly less protection against wild dogs.

 What
causes more economic cost, emus or
wild dogs?
 Answer: emus
 However, research shows the impact of wild
dogs cause greater concern. Farmers are
strongly affected by the distress and injury
that wild dogs can inflict upon their stock.
 Along the Esperance extension the majority
of benefits are expected to arise from emu
control

How much will the fence
cost the landholder
Use the following examples to calculate the cost of your levy:
EG1:
Farm valuation
= $679000 (farm size: 1165.51ha)
UV Rural rate
= $3841.78
Estimated interest rates: 4.4% over 10 years or 2.9% over 20 years
To find cost of SBF levy:
Over 10 years - $3841.78 x 4.4% = $169 (in this case approx. 14.5c/hectare per year)
Over 20 years - $3841.78 x 2.9% = $111.41 (in this case approx 9.5c/hectare per year)
EG2:
Farm Valuation
= $1087000 (farm size 2226ha)
UV Rural Rate
= $6200.25
Estimated interest rates: 4.4% over 10 years or 2.9% over 20 years
To find cost of SBF levy:
Over 10 years - $6200.25 x 4.4% = $272.81 (in this case approx. 12.3c/hectare per year)
Over 20 years - $6200.25 x 2.9% = $179.81 (in this case approx. 8.1c/hectare per year)
NB: Should the amount of your UV rural rate increase, the percentage charged against it will decrease so
that the levy amount remains the same each year. The levy will only alter if the value of the land, as per the
Valuer General's valuation, changes. This may be an increase or a decrease.
Required to gauge community support for the fence
extension project.
 $1.76m to be raised by Specified Area Rate for 10 or
20 yrs across Unimproved Value rate properties.
 The amount contributed by each rate assessment is
determined by the valuation of each property.
 State & Federal Government are not willing to
commit more funds unless the industry is willing to
financially support the project
 If the project goes ahead Government will be putting
in $4 for every $1 industry puts in.

If the Referendum fails the project will not go
ahead. This will be Esperance’s only chance to
have the State Barrier Fence extended to protect
all farming properties in the region.
 The
barrier fence will surround the
Esperance farming region.
 Cost analysis shows a 2 to 1 return on the $
invested.
 The SBF is a long term and more permanent
solution to dog and emu migration.
 Doggers work well when they are
obtainable. No guarantee of availability into
the future.
 This will be the only chance to have the
fence extended.
