Gurney, 'Lucky' Grills is/was a TV personality here in Oz, on a show I have never seen, on a channel I don't watch.
And as for wombats (which are related to koalas - wombats stayed on the ground and koalas took to the trees yonks ago) don't tangle with a wombat. Some years ago my son Stephen The Drummer was travelling back to Sydney very late one night after a gig in Canberra, nearly three hours drive south, when he hit a wombat somewhere near Marulan. (for the non-Ozzies: Marulan is pronounced Mar - roo as in kangaroo - lan) Score: wombat one, Stephen's little blue car nil. $1500 damage to the underneath bits.
I admire wombats and would very much like to have one. But they don't make good pets.
