My experience has been two fold.

One, where they can be hunted legally under destruction permits, they are quite easy to shoot with a rifle. Even a .22 rimfire. Trying to hunt them with a bow is a different matter. While they might sit at 70 to 100 metres to look back making a quick rifle shot easy, they generally know you are there and never let you into bow range. Unless you take them completely by surprise.

However when hunting pigs a few years ago the landowner told us to shoot some roos for him as well and these roos stayed well out and hopped as soon as they saw a human or vehicle. 300 to 400 metres away and they still turned and hopped away.

I have yet to be able to take a nice red roo AND be able to have its skin at home (ie pest destruction does not allow removing from the property). It would make a nice addition to the trophy room. It is absolutely ludicrous that we can't say buy 5 tags for legally harvestable roos as sporting shooters each year. It would not harm numbers either.
