Guys there's something I want to share with you all!! You can now play warzone without vpn in your country, I' m from the Philippines btw. Just try this trick. When opening the game just turn on your vpn and select Australia server then after log in and entering the lobby, don't press start. Quickly turn off your vpn and play start and your ready to go!! Wish I can be helpful to you guys

Update OK ! Australie playstore and vpn and new Google a country. It works for me
