Do we need an Opal card for a short Sydney visit with ferry rides?

A physical Opal card can still suit someone without a compatible payment card; compare the current fare rules and concessions before buying one.

Use the same eligible card or device for every tap by one traveller so any daily or weekly benefit is calculated consistently.

Check Transport for NSW's current fare-cap rules for both Opal and contactless cards; do not rely on an old forum amount.
