These dogs' double-layered, coarse coats don't need a ton of care, so overall Australian Terrier grooming isn't a very time-consuming process. Though they don't shed too much, Aussies' coats do tangle and mat some, so they'll need brushing 3-4 times per week. They'll also need baths about every three months, or if they get particularly dirty or stinky (but be aware that the more frequently you bathe an Aussie Terrier, the softer its coat gets; this shouldn't be a problem unless you show the dog). And some owners clip their Aussie's coat into a Puppy Cut every 3-4 months to make it lower-maintenance, while others hand-strip it.
To brush: first wet the coat with mist from a spray bottle. A pin brush works best on these dogs, and a 2-in-1 comb for working through tangles and mats might come in handy as well. Brush the coat in the typical line-brushing fashion; if you encounter a stubborn tangle or mat, first separate it with your fingers, then finish working it out with the comb. If you're following the brushing with a bath, these little dogs are small enough to bathe in the kitchen sink. Use canine shampoo; apply some shampoo to the dogs back, then lather well and work downward (and don't forget the legs!). Rinse thoroughly, towel- or blow-dry, then give the coat another quick brush-through to make it look clean and neat.
Both clipping the coat and stripping it have their advantages, and both can easily be done at home. (See the Styling & Haircuts section for further details on both processes.) Regardless of which you choose, it's a good idea to visit a professional groomer at least once, as he or she can demonstrate how to clip or strip the coat, and provide tips on how to groom an Australian Terrier in general.
