Hey!
I used to live in Sydney and I currently live in Canberra and from all my research no one sells Earth Balance.
Nuttelex isn't really vegan anyways; it contains palm oil (palm oil and palm sugar are directly linked to the destruction of orangutan habitat).
Your best bet is to go to a health food store and get "Melrose Omega Gold Margarine" http://www.melrosehealth.com.au/health_products/Organic/product_info/products_id/Omega_Gold/35/
It tastes and has the texture of slightly cooled butter (I vaguely remember dairy and I had to question whether I was actually eating butter. It tastes amazing AND it's incredibly healthy for you.
It's a little bit more expensive then Nuttelex but I recommend that to anyone who's after a vegan margarine.
ENJOY!
Just thought id say, i bought the melrose omega gold margarine today... and loved it!
