We do, and that's what we export, but there are also reserves of brown coal which are cheap* and close to Melbourne. *If you ignore the climate cost and unreliability of the aging plants; coal power (both brown and black) in Australia is quite unreliable as the plants are super old and there has been no investment in power infrastructure due to policy uncertainty due to infantile governments. So on hot days, when demand is higher, coal plants break down due to the greater heat. At least you can predict when you'll have wind and solar power available; here coal power is more temperamental.
