Is it hard for a Indian to get a Australian tourist visa?

My friend who's Indian wants to come to Australia for few days on a tourist visa he's a been to Australia before on a study visa other than that he's been to Bangkok, Hong Kong, Macau and mauritius and his father covers all his financial expenses but he doesn't have a job back in India neither has any property in his name but then again he's been to Australia before and to some other places too without any overstay so the only positive he has is that his family has a big business in India so doesn't signify that he will return to his country.
