Watching Arrowverse in Australia is a nightmare because not every season is available on one or two streaming services that are available in Australia. Here is how you can watch Arrowverse in Australia: Arrow: Netflix up to season 7 Flash: Stan up to season 5, and s06e15 is on Foxtel none of the rest of season 6 is there. Legends of Tomorrow: Foxtel up to season 5 e8 Super girl: Foxtel up to season 5 e16 Black Lightning: Netflix up to season 3 Batwoman: Foxtel season 1 to e16. However, there is a way to watch Arrowverse in Australia as it is available on the CW, which is completely free. But it would be best if you had a VPN (Virtual Private Network) to access all the seasons and latest episodes of Arrowverse on the CW in Australia, as the service is only available in the USA because of streaming rights issues.
