So this is some bollocks. Guess I'll be cancelling our plan since it's only used by two of us.
Current price $17.99/month, new price $32.99/month.
If they boiled the frog better I would probably have accepted a $5/month price rise, and then another later... But close to doubling in one go is a no from me dawg.
Thank you for being a loyal member throughout our journey. We created YouTube Premium so that you could enjoy all the videos and music you love without interruptions.
To continue delivering great service and features, we are increasing the YouTube Premium family plan price to A$32.99/month. We don't make these decisions lightly, and this update will allow us to continue to improve YouTube Premium and support the creators and artists you watch on YouTube. This is the first ever price increase for your subscription.
