I was invited to submit some designs to the Secret 7" initiative for 2016, having had one chosen in the 2015 round, so I sent a few off. Last year there were about 5000 entries, including designs by Yoko Ono, Martin Parr and David Shrigley.
CERES Harvest Festival
Every autumn, the CERES Community Environment Park in East Brunswick has a Harvest Festival which involves lots of fresh fruit and vegies, demonstrations of all things green, musicians and storytellers, roaming chooks, face painting (not just for kids!), a cake competition, people riding tall bikes, compost making activities (mostly for kids) and the odd pig.
