I need to find the expected return of Woodside petroleum based on using 2019 data (not including 2020). The beta =0.37 from a regression line i made from 2015-2019 (5 year monthly regression plot against the market index which is the asx 200. This needs to be based on Australian values the issue I'm having is finding the risk free rate which I'm pretty sure is equal to a 5 or 10 year treasury bond (in AUSTRALIA) and solving for the market risk premium ? The image attached is what i found but I'm not sure of which value I'm supposed to use and if it has changed from 2019 to today. The overall question is can someone help solve the expected return of woodside petroleum ?
