This is more of an aussie pub yarn than a joke but still funny.

Fred was talking to a couple of other stationhands at the pub and the topic got onto the hardest muster they ever done. The were a good 50 000 head of cattle, 60 000 head of sheep. Then it came to Freds turn. He said "The hardest muster I done was taking 200 000 head of goanna overland from darwin to hobart. We set out from darwin in about a week we was in the desert. The sand burnt the goannas feet something shocking so the we decided we had to do something. Clancy and Bluey, the other two blokes on the trip, left me with the mob and went into the Alice to get some shoes for the poor little blitters. They came back with sardine cans for the little buggers to wear on their feet."
"Then what happened," asked the enthralled listeners in the pub.
"We set of again, the shoes we had got for the goannas made such a noise that I reckon they heard us all the way to the Kimberly."
Fred continued with his tale.
"Any ways, we came to the snowy mountians three weeks after that. The weather had changed and it was starting to snow as well, as we started up over them ranges. We decided something must be done to save the goannas. Bluey and Clancy set of and left me with the mob again. They came back in a week, they been down to Thredbo and bought back a little scarf for each of the goannas. About a week later we had them in hobart."
One of the enthralled listeners asked while fred was sipping his beer, "How did ya get them over bass straight Fred?"
Fred looked up and replied, "Well, we didn't go that way."

Australians the masters of BS like that.
