Optus Sport has handed off the rights to all their content over to Stan, effective 1 August.
Having a look at SubHub, it looks like there is a deal for Optus customers to sign up for Stan at a discounted rate that includes all of Stan's content up until January. If I'm reading the FAQ right, the $9.99/month will still be charged after January but you'll lose access to everything else (I'm assuming that means Stan's current sport offering).
Note that this deal is for new Stan subscriptions only, it seems. It does say also for returning but according to the A-League subreddit, there have been issues with signup up using existing accounts.
Relevant bits of the FAQ:
Will I still have access to Optus Sport on Stan if I’m no longer with Optus?
No, Optus Sport on Stan is only available to eligible Optus customers while you remain an Optus customer. If you cancel your eligible Optus service/s, your Optus Sport on Stan subscription will be cancelled at the end of your current Optus subscription cycle, and you won’t be eligible to re-subscribe. You will be able to access the same football content by subscribing directly to Stan Sport.
What happens to my Optus Sport on Stan subscription after January 2026?
Your access to Stan Entertainment and Stan Sport ends on 8 January 2026. After that time, your Optus Sport on Stan subscription will only provide access to the Optus Sport football content and you will continue to be billed $9.99/month.
Can I choose to not activate my Optus Sport on Stan subscription today and sign up later?
Yes, you have the option to access Optus Sport on Stan any time before the end of the 2027/28 Premier League season by subscribing via SubHub, provided you remain an Optus customer with eligible services.
Hmm, so on SubHub it says: Includes Stan Premium + Stan Sport until Jan 2026. Available to new and returning Stan customers
Yet at checkout as a returning customer I get quoted the full price :(
