I noticed this deal is back: https://www.ozbargain.com.au/node/493041
From the apple site: Students enrolled in degree-granting universities and colleges can join Apple Music at a discounted monthly rate for up to 48 months. And if you have an Apple Music student subscription, you also get Apple TV+ for a limited time. To qualify for an Apple Music student subscription, you must be a student studying a bachelor degree, postgraduate degree or equivalent Higher Education course at a university, college (US only) or post-secondary school (Canada only). Junior, technical colleges and special courses are also eligible in Japan.
The instructions weren't quite right in practice. I had to subscribe to Apple Music (was offered a trial, but if you are a current subscriber you can change to student), then go into subscriptions in settings and change it to the student rate (after Unidays verification).
You can check on Unidays if you will get through verification, before you commit.
I already had an AppleTV account, which I have cancelled. Hopefully free AppleTV kicks in automatically!
Second deal posted. Hope I did it right.
Note
Getting Apple TV+ through this offer will give you a SINGLE USER account, standard paid for account or offer given with new apple device allows up to 6 users/watching at one time.
Cheers.
Does an student subscription allow family sharing of Apple Music?
