That is exactly what I did to confirm what I believed to be true, before I posted the information here.
Australia will allow it's citizens to return home on any date that their passport is valid.
Indonesia requires you to have 6 months validity on the date you arrive in Indonesia. You will obviously need a valid passport to leave the country but a passport is still valid until the day it expires.
