Don't know if it's available down under but here I always recommend Carnation Instant Breakfast VHC, which stand for "very high calories". Try the internet. It has 560 cals in an 8 oz can.

IMO he needs 3000 cals a day and separately at least 48 ozs of water. Even with that he will probably loose weight as this Tx is a bugger as you strange talking people would say. lol

As his Caregiver, toughest job in the world, you must treat him like a kid and make sure you track his daily intake. Since I am an expert on not getting enough calories and water during Tx I can tell you REALLY BAD THINGS WILL HAPPEN TO HIM if he doesn't get the necessary calories and water in him EACH and EVERY day from now until at least a month POST TX.
