Since Kodak discontinued their famous HIE infrared films, We couldn’t find any infrared film has that high wavelength up to 900nm. However the last true infrared film Efke IR820 also has been discontinued. 
Just got the IR820 films from Europe, hope its qualities would not be affected on shipping in that hot weather in Australia.When the package arrived, it was labeled as No X-Ray, which is good. I couldn’t wait to test those films.
