<<Disclaimer: Verify this information before applying it to your situation.>> I cannot comment on the availability of gluten free xanthan gum or gluten-free yeast but there is a wide range of gluten free products available in Australia including Baking powder, breads, cereals, pastas, flours etc. Generally they are available in most health food stores, although some major supermarkets seem to be now catering for the gluten intolerant community. I suggest you try the local `Coles' Supermarket before the health food shops, as prices are significantly lower. Again, the availability in these supermarkets seems to be dependant on the locality. In some areas there is a demand and others there is not. As far as restaurants are concerned, there is a problem. No one seems to cater for celiacs and there is a marked ignorance even concerning the problem. The best bet is to locate something on the menu that seems to be okay and then ask!! Be very specific about what is harmful to you. I find roasts can be safe if gravy is not served. Also fish just grilled in butter, no flour but remember to state, "no flour" Anyhow, I have a list of acceptable foods released by the Celiac Society here in Sydney but lack access to a scanner. I can either post a copy to you in The States or forward one to your address in Australia. BTW, I can only speak from my knowledge in Sydney, perhaps if you post where in Australia you will be honouring us with your company, others may be able to assist you. All the best, I hope you enjoy the heat- its Summer now you know. Depending on your destination it won't start to cool off until April. Graeme Roberts [log in to unmask]
