Is Wallaby Organic Yogurt semi-healthy?

I really like they're "Down Under" line of yogurts... If your not familiar with this brand, its bically just an organic line of austrailian yogurts... I'm pretty smart when it comes to nutrition, and I know that just because somethings organic, doesn't means its necessarily healthy. The one thing that gets me is the high sugar content of 23 grams, BUT it isn't refined sugar. The ingredients say naturally milled organic cane sugar, which is one of the best sugars other than natural sugars in fruits and compared to others. Other than that it seems very healthy, there are only like 6 other ingridents (Just organic milk, organic mango, stuff like that)... So is this healthy or is the sugar a bit to high? I really don't eat many other sugars other than natural sugar in fruits, veggies, whole grain pastas, ect...
