The Mastiff is a large-sized dog with low energy needs. Those two things — the space it needs and the exercise it expects — matter more day to day than the breed label itself, especially with rescue dogs, where many are crosses.
Shelter breed labels in Australia are usually a visual guess rather than a DNA result, so a dog listed as a Mastiff may well be a cross. That is worth knowing before you rule a listing in or out: temperament and the individual dog's history tell you far more than the name on the card.
Right now Mastiffs in Australia are listed by Animal Welfare League NSW, Animal Welfare League Queensland, Blacktown Animal Rehoming Centre, Dogs' Refuge Home, Happy Paws Haven, K9 Dog Rescue, Monika's Doggie Rescue, RSPCA NSW, RSPCA Queensland, Sydney Dogs and Cats Home, The Lost Dogs' Home. Applications, home checks and adoption decisions are handled by the rescue directly — LocalPetFinder brings the listings together so you do not have to check each rescue separately, and does not take a fee.

Every listing links straight to the rescue that has the dog, and the application is handled by them, not by us.
Not for sale, for adoption, which is usually the better deal. Every Mastiff here comes from an Australian rescue rather than a breeder or a classified seller, and the adoption fee already covers desexing, vaccination and microchipping. That fee is typically a few hundred dollars, against often several thousand from a breeder with none of the vet work done. If you searched "mastiff for sale", adopting gets you a vetted dog for a fraction of the price.
