An old Australian expression meaning to hurry up. Has its origins in the crusted dry dags that gathered in the wool around a sheep's rear end. When dry and hardened they rattle when the sheep runs. Commonly prevented by what is called crutching or shearing the wool around the rear end of the beast.
An expression brought back to Australia from Palestine after First World War by returning soldiers. This expression has its roots in the Arabic word 'shufti' (sic) and means in Australian slang to have a look or have a peek, usually at something out of the ordinary.
Hey mate, take a crafty shufti at that piece of crumpet.
