A good question.
A local answer.

Choose the venue that fits your travel route and the experience you want, then confirm booking and age restrictions. Avoid crossing the region twice for similar stops.

Compare the current koala program, age limits, duration and total family price on each venue's official site. Encounter formats and welfare rules can change.

Price the car ferry against travelling as foot passengers and using island transport. Book an early outward and realistic return slot if taking the vehicle.

Check stroller access, shade and changing facilities for each attraction before paying for tickets. A ferry ride can be a pleasant activity by itself if the weather is kind.

Confirm the ship's exact Brisbane terminal and all-aboard time first. The terminal location changes the transfer plan substantially.

If city dining and museums matter equally, split the stay into two blocks rather than commuting back and forth every day. Allow one lighter day between major attractions.

List your island accommodation, ferry terminal and intended beaches. A car adds flexibility, but a vehicle ferry needs its own booking and cost.

Compare the operator's actual departure point and total travel time from your hotel, not only the time on the water. Check the season and current sailing dates.
