Foxy: And comparing fish who by their very nature can survive and breed in their native habitats with animals bred in captivity with no survival skills is rather lame.

Ok... I was that time. Xin loi.

You are wrong, cat & dogs by their very nature do very well, so do rabbits, even pet ones. And yes pet fish do very well too. I think their are enough studies to show the native animal decline. The Carp & Tilapia are extremely destructive. You're a Greenie you should know this, or is it a case of I don't want to know about the stuff I like.

Feral pigs & Goats in North Queensland have been extremely destructive. We got 70 pigs at one waterhole near Lockhart one evening. Exercising with live rounds in that part of the country. We got 120 Goats near Ravenswood another time. There ain't nothin' like a 60 to clean things up. ;-) Did some horses in the 60's out near Warwick. Got in the $hit for that. Someone dobbed us in to the papers. "Army shoots wild Horses."

There are also statistics on feral camels too. They were domesticated when they were turned loose so were the horses.

If you get onto the CSIRO, they have a website for that sort of thing.

Meanwhile, in the complicated world of animal liberation and animal protection,

Dear OTB,

Once again you get in with your boot first
and then comes your righteous indignation.
You say you're not going for tit-for-tat
and then proceed to do precisely that.
Tsk. Tsk.
And again what makes you think that I would
buy overseas products in preference to Australian.
I prefer quality and I can afford it.
That's actually a very sore point with me.
I firmly believe in supporting Australian farmers,
and Australian manufactureres. I have family
members who are farmers and I come from farming stock
from way back. I prefer our local produce to anything
garned from overseas. And I have always supported
locals, be it in food, clothes, or anything else.
So don't you dare insinuate things about me that
you know nothing about you self-righteous hypocrite.
Accusing me of things when you lead the parade in
putting the boot in .

That can go through to the (wicket)keeper too.

Foxy, rabbits are banned in Queensland because Campbell Newman will not allow anything more intelligent than himself in the State. Joh Bjelke-Petersen banned cockroaches from coming north, for the very same reason.

I am in favor of proper feral animal control. Such controls should be left to the professionals, and not be placed in the hands of "the gun happy brigade' as some here in NSW are attempting to do. The political arm of this minority group represented by the Shooters Party has been attempting to have "recreational shooters" allowed into national parks and other public spaces to "control" feral pests. The trial of this recreational cull by these amateurs proved to be an expensive disaster, costing an inordinate amount and achieving nothing.
Feral animal control by all means, but keep the "Weekend Rambo's" on the side lines, leave it to the professionals, and allow the majority to enjoy our national parks and public spaces.
