Where can i watch seasons 3-8 in the us?

Are there any websites i can watch it on? So far ive seen that only youtube has it but its 1.99 per episode and it only has season 2 available to purchase. Also, on youtube wentworth has a youtube channel and posted season 1-2 for free but they cut out so many scenes and blurred out every scene with blood, and they dont have the other seasons.
