I have a theory on this. I would bet that the sausages he had bought were not Aussie snags but a South African sausage called 'boerewors' (Yum !) It is a long coil of sausage and if you remove it from it's casing (skin) it is very much like mince. It plays a huge part in African barbeques and depending on who's made it is usually delicious !
I could be wrong tho....
Surely Zim is not short for Zimbabwe, LOL SORRY!
