Dog fences

["Graham Turner" <>]

G'day Birders, art Easter this year I did a trip to SW QLD including Bowra 
and west to SA (sorry, never did get around to posting a trip report, 
needless to sat it was fantastic). At several spots along the road we 
encountered 'dog fences' eg NSW QLD border and  west of Thargomindah. Does 
anyone know why these fences are still maintained? I mean there are 'dogs' 
on both sides of the fence. At one point (Bullo Downs Road) we saw a forlorn 
looking Emu peering through the fence, knowing the grass must have been 
greener on the other side.
Can anyone enlighten me on the value of these fences.

Thanks
Graham Turner
