The website www.art-prizes.com features information, dates, updates and news about international and Australian art prizes. This is incredibly useful, as previously you could only learn about prizes by doing detailed web searches, seeing the ad in an art magazine or coming across it some other way.
The site has a calendar for every month, displaying the submission dates for each. You just click the link for the prize you’re interested in and it takes you through to the information and submission pages.
They also have Facebook page and other social media presence and an app for your phone which is free.
