@Sister
I am a little envious of your koalas and echnidnas.
We have more birdlife than animal life on our block. We have the reptiles - skinks, house geckos, blue tongues, bobtails,
gilberts dragons, bungarras, frill neck lizards and snakes of course. There is a very large olive python living in the shed and many "cheeky" snakes (King Browns) are often observed. The olive python often hangs off the rafters watching Ian "create".
However apart from the very cute agile wallabies not much else in marsupial life. A girlfriend who lives some 5 blocks away has a family of echidnas at the back of her block where it backs onto bush. Some years ago there were northern quolls visiting, however the neighbours aquired themselves some very large pig dogs and I haven't seen the quolls since.
Very relunctantly we fenced the agile wallabies out of our block. They were doing much damage to the garden and reticulation. We seemed to spend much of our precious Sunday off repairing reticulation lines that had been dug up or chewed off.
However the wallabies did have retribution. After a weekend of fencing some 500 metres of pig wire topped with 3 rows of barbed wire, there were many cuts, scratches and barked knuckles. That was 10 years ago - couldn't do it now!
