March is pretty good. Students are mostly back to school now, and weather is not too bad. Try to avoid school holidays in Australia, which will increase your cost of accommodation. Also, do not travel during Chinese new year or other Chinese public holidays, flight tickets are considerably more expensive. July to Sep is a bit too cold to travel around.
Spring and Autumn seems a good choice. Just sneak off the public holiday time of China and you will be fine. March and November is a very good choice, and the price of the flight will be fascinating. Only around 4500 CNY if you transit at HK by Cathay Pacific.
机票,你得看你运气,能不凑别人的热闹最好,比如寒暑假,国庆春节,国人的出游高峰,圣诞节,土澳欧美的出行高峰。另外,澳洲学生有春秋假,四月中下旬,九月下旬到十月上旬,那也是他们家庭度假的高峰,住宿都不好找。
