Just got home from a day out with my pat frank and never had to dig once, yet got a few , its different country here and as you know we dont have the deep dens like they do in the uk , in the country I hunt, old rabbit warrens are the norm in shallow sandy soils , under old farm houses and haystacks , I'm on the southern plains/riverena. And since a fox pelt has become worthless , farmers welcome you onto their land , it would be embarrassing to put a acre figure on the country I have access to . Suffice to say your little state of victoria has a greater land mass than all of the british isle
