Panasonic cordless phone KX-TG6821
Phone is as new as I used it only for a few month as a spare phone. Only the box is slightly damaged (image layer peeled off in a not so successful attempt to remove a sticker; see pic). Works well with NBN specs : https://www.panasonic.com/mea/en/consumer/telephones/telephone/cordless/kx-tg6821.html#specs
