All the particulars are up to you, dear.. If you want to put in extensions to get twists go for it!
I just saw the movie "Human Traffic" with an actress called Lorraine Pilkington who had the most gorgeous angelic blonde curls.. maybe you could attempt her hair style with extensions.
And since you're in Australia I have no idea where you would get the extension hair from. I would imagine a salon would be a good place to ask, but other than that I'm clueless. Also maybe you could try bantu knots.. I consider that a "twisted style" too.
ETA: Also check on the net to see if you can order some hair..
Yay! You look lovely with the kinky twists, and your own hair has grown so much. Yes, I (stalk?) keep up with your progress.. lol
