Help with Koi Food

Hi all

Was wondering what everyone's experience with the product below is? I have about 6 smallish koi (5-10cm in length) and wondering if this would be a good food option for them or if anyone would recommend a different product?

I'm in Sydney Australia if that makes a difference. Thanks.
