Aussie for hurry up. Dags being the shit stuck on a sheeps arse. They rattle when they run.

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.

Get a move on; hurry up. From sheep dags, being crusty bits of dried crap stuck to the fleece around the bum, which rattle as they run.

get a move on. (Australianism)
