My husband is an Australian Chinese and now works in China. Can you help me apply for an Australian green card in China? Do I have to live in Australia after applying?

You can apply for an Australian green card in China. As a spouse, you can do it. If you have been married for 7 years and have children, the Australian government will give you a one-stop green card, valid for 5 years. After five years, you hesitate that your husband and daughter are both Australian nationals, so you have tie with them, so you can renew them unanimously, but you can only renew them in 1 year and 1 year if you have not lived for two years in five years.
