Yes. The Watch NRL service is designed to provide Live and On-Demand access to every match of the 2023 NRL Telstra Premiership (as well as previous seasons).
If you've missed the kick-off of a Live stream and want to catch up, you can choose to 'Play from Start' or 'Play from Live'. Watch NRL customers also have the ability to rewind Live content, meaning you have total control over how you watch the match.
If the Live stream has ended, a full match replay (ad-break free) will be uploaded to the Watch NRL service. Every match from every round will become available On-Demand approximately 4-8 hours after the completion of the match.
