looking for a fridge as well. have done some research so thought might as well share it here.
my criteria is: between 300-400L and below $900. the prices are indicative (from harvey norman) only. you probably can get cheaper from the neighborhood shops.
the list is not exhaustive. if you know of other brands/models that fit the criteria, please share!
