Telstra NBN Avaliability

I live in Wudinna, South Australia 5652 and was wondering whether we will be able to access the NBN through Telstra, as there is currently Skymuster avaliable however i am not very impressed with their bundle offers avaliable. i currently have ADSL+2 bundle which gives me 1000GB of data, unlimited calls to local, STD & mobiles around Australia all for $99p/mth however i have had a look at the companies offering internet through skymuster and they dont compare at all. Why would i want to change over to SkyMuster when im receiving such a better deal through Telstra. Can you please explain to me Telstras plans for the NBN in my area and will we be receiving similar or the same kind of bundle offers as im very happy to stay with Telstra and dont want to move over to another company. Cheers
