Mark,
In many areas they are considered a pest! They are a Pest in much of my area, though it depends on the season. We are not allowed to just go out and shoot them, you have to apply for tags... This means getting the Agriculture Dept to do a survey of your property, then they will tell you how many you can cull! People do hunt them on the quiet though... Most of the culled Roos go for Pet meat, however some does end up on the Restaurant table! It is a very lean meat and when I have had it as a roast, I have been very impressed.
During the 1940s, 50s, 60s and into the early 70s many .303 military rifles fired a .303 case necked down to .22 and .25 for Roo shooting... Some great looking rifles floating around in these conversions. I am actually thinking of collecting a few. Some of the more unusual chamberings on the Military .303 were .303-243 and .303-270... You can pick them up from $50-$300 Aussie [$25-$150 U.S]... makes for interesting Aussie shooting history!
Roos are one of the success stories with the introduction of man... We cleared the land, planted improved pastures which they thrive on and then culled the Dingos which were their main predator, alongside the Aboriginie... Aboriginals don`t hunt much anymore, so the Roos have thrived. In some areas they have thrived to the stage of starvation, especially when drought hits!
I have quite a few here on the Ranch/Farm... Is always nice to have a few. However when they come thru in big groups, they do a lot of damage to fences and crops. Not just what they eat, but what they knock down when moving about, playing and fighting. My neighbours have them in goups of up to 60 or so. When they head for my place a few shots over their heads and they go back for a week or so
This goes on and on thru-out summer and Autumn...
When last in Texas, I was amazed to see Kangaroos roaming ranches there. One Rancher I know there captive breeds them very well.... He told me things about Roo breeding I didn`t know! hahaha... As for me stocking a ranch with them - well,,,,,,,,,, I do like them but I don't think enough to deliberately introduce them
cheers,
Cam....
