Lunar new year is probably the most celebrated holiday in Asia, in Australia, Chinese and Vietnamese communities celebrate lunar new year with lots of festivals. Last sunday the festival was in Richmond, where there is a strong Vietnamese community. The festival is mostly about food, lots of street food stalls selling meat skews to sugar cane juice, the festival will go on for another 2 weeks until end of lunar new year celebrations, anyone who is interested in good food should have a look at this website for details:
