The Opera House is NSW's essential image, but it earns more than a harbour-side photo: see it from the water, around Circular Quay and from the Botanic Garden, then take a tour or attend a performance if timing works. A guided interior tour gives useful architectural context; the exterior and precinct are worthwhile even without one.
1.5h Book aheadWalk the forecourt early in the morning, then return around sunset for the harbour lights.
Tours and performances should be booked ahead, especially for weekends and school holidays; exterior access is free.

Sydney's other defining landmark is most rewarding as an active part of the city rather than a distant photo: walk the pedestrian path between The Rocks and Milsons Point for the Opera House view. The BridgeClimb is expensive but genuinely memorable for travellers who want the full-scale harbour experience.
1.3h Book aheadUse the pedestrian walkway at first light or late afternoon; book a twilight climb early.
The bridge walk is free; reserve BridgeClimb sessions well ahead for peak dates, dawn and twilight climbs.

This is the most accessible big-landscape escape from Sydney: sandstone escarpments, eucalyptus haze, waterfalls and the Three Sisters make a very different counterpoint to the harbour. Stay a night around Katoomba, Leura or Blackheath if possible, since a rushed coach day trip misses the quieter walks and changing light.
8h FreeReach Echo Point at sunrise or late afternoon, and walk beyond the main lookout before mid-morning coach groups arrive.

Lord Howe combines a dramatic volcanic skyline with unusually clear lagoon water, serious hiking and a deliberately low-key, low-capacity island rhythm. It is a destination in its own right rather than a Sydney add-on, ideally with four or more nights to allow for weather and boat-dependent activities.
72h Sells out — book weeks aheadThere are no city-scale crowds, but book flights, accommodation and Mt Gower guided walks as early as possible.
Flights and the small number of beds routinely fill months ahead, particularly in school holidays and warmer months.
The eroded Walls of China and Lake Mungo's deep First Nations and archaeological record make this one of Australia's most significant inland landscapes. It is remote and works best on a self-drive western NSW itinerary; take the ranger-guided experience if available rather than treating it only as a scenic stop.
5h Walk upGo at sunrise or late afternoon, when the formations are at their best and summer heat is less severe.
Park entry is generally paid via a NSW parks pass or on arrival; guided tours and nearby accommodation should be arranged ahead in busy periods.

This is the easy, free way to turn the Opera House and harbour into a proper half-day rather than a checklist photo stop. Walk through the gardens to Mrs Macquarie's Point for one of Sydney's classic city-and-harbour views, then continue to Circular Quay or the Art Gallery precinct.
1.5h FreeMorning is cooler and quieter; come near sunset for the view from Mrs Macquarie's Point.

This is one of outback NSW's strongest landscape-and-culture stops, centred on the rugged Mount Gunderbooka range, Aboriginal rock art and wide-open red-country scenery. It is best used as a self-drive overnight or two-night detour from Bourke rather than a quick stop; come prepared for distance, heat and limited services.
8h FreeVisit in the cooler months (roughly April to October); early morning is best for walks and heat.
