You cannot buy gluten free oats in Australia. Under the current Australian food labelling laws there are no 'gluten free oats'. Please confirm which brand of oats you used in this recipe which are 'gluten free'?
Hey "Test" I buy them online through this company http://wheatfree.com.au/Oats and I know there is lots of other Australian online health food stores that supply them as well feel free to look it up. If you have any concerns you can just use GF flour of course.
