Can a Sydney sider please advise if the Sunday $2.50 fare is available as a once off Opal single ticket purchase or do you need an Opal card ($10 min deposit) to take advantage of the $2.50 cap?
I will be in Sydney on Sunday only and Opal website and $2.50 deal post here isn't 100% clear.

Opal card benefits
The more you travel with an Opal card the more you can benefit. And these benefits affect how your fare is calculated. For example, if you’ve reached your Weekly Travel Cap, your fares for the rest of the week are half-price.
You can’t earn Opal card benefits with an Opal single trip ticket, because these tickets are single-use only. Find out more about Opal card benefits.
