Yes, you can use Optus Sport on your Amazon Fire TV Stick. In order to do so, you’ll need to download the Optus Sport app onto your Fire Stick device. Remember, Optus Sport is only available in Australia. If you’re traveling abroad, you’ll need to first connect to a VPN (most of the VPNs in this post offer apps for Amazon Fire TV and Fire Stick), connect to a server in Australia, and you should be all set!
