Hmmmm.....and I thought our wild deer were becoming a problem.
It was ten years ago when wifey and I were in Perth on seafood (lobster importer) biz, and we were invited to "the farm and winery" for the weekend, well inland....got to see tons of those pests bounding thru the vineyards and across the roads.
We were warned that were we to drive in the countryside (fat chance....wrong side of the road over there) at dusk to be on high alert for 'roos crossing.
