Try Bizarre Pets in Waverley (Eastern Suburbs) they often have rats/mice on the go. THeir number is in the phone book but escapes me at the moment...call them first as they are a little bit erratic regarding live stock but they can at least give you an idea when they will have some due.
when i swiched my coastal onto thawed i gust wiggled a thawed mouse infront of it and it ate it. i reakon gust make your snake hungry by not feeding it for a few weeks then give it some thawed ones.And i have live pinkies if your ever in country nsw.
It will actually be both. I am going to feed the male with mouthrot on saturday once he has fully recovered and then the female as well which now will only eat live pinkies.
