Two of the things you will see when at the GZ of the cache is a
huge welcome to Mulwala sign on a slope across the road, the 2nd is
the huge lake that lies just a few meters from the cache!
As most people will know, Lake Mulwala is acctually the Murray
River. Just a while down from the cache is the huge weir which
floodes the lake, you can see the impact the weir has made on the
river with dead trees scattered all over the lake!
The lake is also a popular fishing location. There are many
kinds of fish to catch here including the Murry Cod.
But one of the most seen things on the lake is the speed boats
towing skiiers, boarders and people on huge floating divises, i
found out how much one of those floating things can hurt you, I
walked away with a pulled back, pulled neck and a badly pulled
bicep! But it was still fun!
Welcome to Mulwala! 
Lake Mulwala from GZ Cache is hidden in a manner familiar to most
cachers.
Good luck and have fun!
