You need to apply for a China visa to go to Guangzhou (Canton). If you obtain visa in India, you should provide the original and a copy of your permanent residence or work permit which should be valid for at least half a year (except for those who are visa or permit exempt for residing or working in India); Otherwise, please obtain your visa in Australia or Hong Kong, then go to Guangzhou.
