There may be grants for software development offered in Australia. However, the choices that are available depend on when you search. Each year there are different offers available, and also the choices change within the year because the programs have their own deadlines. It is best to start your search for grants when you know what you need to use the funding for and how much you need. This is so that you can narrow down the offers based on their intended uses. Also pay attention to the eligibility requirements, as they are also different for each.
