The forest here is
overseen by a tattered clan of wallabies. White-chinned, ginger-tummied, they
pause still as stumps when I walk through the bush, watching to see if I’m
trouble.
They come through my
block daily, munching, paws-down, on the deep grass near the pond, or nibbling
my Elderberry bush on their way past the living room.
What they love best,
though, is my orchard.
For four long years I’ve tried to grow fruit trees, and for four years the wallabies have feasted every spring and summer on lush green-tipped sapwood.
At this point, wallabies stop being cute and start being expensive. They’ve caused the demise of plenty of trees, including, last year, an olive and a barely-leafing quince. Christ almighty, they love that quince.

At this point, wallabies stop being cute and start being expensive. They’ve caused the demise of plenty of trees, including, last year, an olive and a barely-leafing quince. Christ almighty, they love that quince.
So this spring, I
decided to properly fence the orchard. It started with scraps of fence filched
from friends, and bought strandwire and pickets. I made it over a weekend in a
race against time as buds began to swell on the boughs, and was pleased enough
with the results.
This, I told myself, running my gaze down the taught silver lines, is a fence.
The wallabies
disagreed. They skipped lithely over it, in the beginning not even for the
trees, but for the kangaroo grass that grows between them. Over a series of
weeks I added strandwire above, slowly growing the fence higher like a coddled
plant drunk on the spring cocktail of sunshine and rain.
“More wire,” I’d instruct
the man at the hardware.
“Well, if you’re doing
your own fencing, you’re doing alright,” he replied on the first afternoon.
“Ha,” I laughed
mirthlessly. “You haven’t seen it.”
On later visits he
began regaling me with stories of eight-foot wallaby fences, made at exorbitant
cost.
This week, after
spotting a wallaby tenderly nuzzling the pink limbs of my apricot tree, I added
the final strand. Now my pickets have wire to their very tops. There’s nowhere
left to go. The fence has reached its limit, and so have I.
My plan B? Try to
outgrow the munching with manuring. Plan C is sacrificial decoy trees. Plan D
is electrified razor wire, and sentinels with searchlights.
It pays to think
creatively when it comes to wallabies.

Vertical alone isn't the answer. A 1ft extension on the (almost) horizontal, angled towards the wallaby's approach will cause it to drastically reassess its trajectory. Now it must achieve both distance and height.
ReplyDeleteIf that's not enough, I know from previous experience that the windscreen washer pump from a VN or VK commodore is about the best bang for buck as far as high pressure, instantaneous delivery, extremely cheap water pumps go. You'd need a pump, a water supply, some 4mm irrigation misters (or jets), a few 4mm one-way valves (to keep up pressure for instant spray), an IR switch w/ reflector (hacked from a door buzzer in a 7/11 or Crazy Clarks), a relay to switch the pump, and a 12v power source. You can also put in a level sensor on the water source ($11) to ensure the pump doesn't run dry.
The sight of wallabies attempting to clear a horizontal extension of a tall fence, only to clip it, hit the ground, and get blasted with water would likely be a satisfying accompaniment to whichever cocktail the weather dictates.
