He recalls in 1955 and 1956 it was very wet and the truck he'd use for roo shooting would get bogged, so in 1957 he was only rabbit trapping.
The humaneness of non-commercial roo shooting has come under fire this week.
In much the same way that steers yield far better meat than cows in beef cattle, young male roos make the best eating.
Meanwhile, however, as they cleared the land and created and improved watering places for livestock, the settlers enabled the roos to multiply exponentially.
She says once she was driving through a National Park and recognised one of the roos to be Jack, a joey she'd reared years earlier.
We began by putting up a high fence, to keep out the roos and the emus and the goats.
But he used to bring me any joeys, he was very careful what roos he shot, mostly the bucks, but if he shot a doe and it had a joey, he would bring that to me.
I said, No, I used to, we used to shoot rabbits and roos and stuff, but we haven't been, it's just the target shooting.
Unfortunately quite a few were killed by vehicles but if grazing had been effective on neighbouring paddocks, many of the roos would have been saved.
The Australian government has declared open season on roos .
