Abstract
This paper presents the condition of COVID-19 in Australia based on the data of each state and territory. The whole population of Australia can be separated into several groups, which are Susceptible, Exposed, Infected, Recovered, Healthy and Unknown by using the extended SEIR model. According to these groups, policies that are published by Australian governments can be divided and matched with groups based on different purposes. After doing diagnostic, predictive, prescriptive analytics and text analysis to the information of the current situation, the author provided seven recommendations that may help improve the current condition of Australia and flattening the curve of total confirmed cases of COVID-19 in Australia.
