Off-peak is from 9am to 3.30pm, after 7pm weekdays until 3am the following day and all day weekends and state-wide Queensland gazetted public holidays.
go card users save 20% travelling during off-peak.
What if my journey starts in off-peak but finishes after off-peak (or vice versa)?
It's based on when you touch on.
If you make a multi-trip journey across standard and off-peak fare times (that is, you are transferring between services) your go card will automatically calculate the fare for you as a mixture of normal and off-peak.
