No one anywhere - in Australia or outside of it - may own a platypus.
To begin with, the platypus has very specialised needs, and unless one has access to large areas where the platypus environment can be recreated, a platypus kept in captivity will surely die.
Further, Australia has a great deal of respect for its native species, and does not generally allow the keeping of native mammals as pets. Licenced carers may temporarily care for these animals, but it is illegal to keep them as pets. Many people in rural and semi-rural areas feed native animals such as kangaroos, which are always free to come and go. However, it is illegal to keep pet kangaroos, wallabies, platypuses, echidnas, sugar gliders, koalas and almost all other species.
