A good question.
A local answer.

Because tournament dates concentrate demand, book a refundable option early. A suburban base can work if the daily drive and parking near the fields are manageable.

For evening meals, check the walk from the exact building to restaurants open on your travel nights. A central label does not guarantee a lively block after hours.

Compare Kingston, Manuka and central addresses by the exact cafe walk and drive to your priority museums. A pleasant dining base may be more useful than staying beside one institution.

Choose a steakhouse that lists the cut, weight and cooking approach rather than relying on a generic 'best steak' list. Call to ask what is available on your night.

A few nights can cover the main city sights; a longer stay makes sense if you add regional walks or day trips. Do not fill every cold day with driving.

Compare the main highway route through larger towns with the shorter inland options, focusing on curves and road conditions rather than distance alone. Rural shortcuts can be narrower or rougher.

Plan each cluster of sights together and check its current car-park map. Availability and time limits vary by institution and event.

Choose two or three priorities, then check their opening hours and booking requirements. Many buildings need more time than a quick photo stop.

Compare central hotels and airport-area options using both transfer legs, not just the room price. A central base may have easier meals and a short airport ride.

Compare current door-to-door schedules and total fares for your flight date. A bus to the airport can be simpler than rail plus a Sydney transfer, but timetables vary.

Reserve a table for a group and confirm whether the performance is indoors, outdoors or ticketed. A quieter venue may be better for conversation.

Use Questacon as a substantial outing and pair it with one short outdoor stop. Check timed entry and the children's energy before adding another museum.
