Yes, you can watch Gutsy on Apple TV. The documentary, whose release is imminent, will be readily streamable for Apple TV+ subscribers in Australia. But if you’re outside the country, there’s no guarantee that you’ll find the title in your specific region’s Apple TV library. Therefore, get an ExpressVPN subscription and enjoy!
To avoid getting errors on your screen, you’ll need solid VPN connectivity through a quality client such as ExpressVPN, which you can take a risk-free trial of for 30 entire days (backed by a full refund guarantee) and can combine with Apple TV+’s free 7-day trial.
