Sydney + Australia in 2 Days on a Budget
Two days: one day on the harbour, one on the train to the Blue Mountains
Two days only stretches to one real day trip, so make it the cheapest and most DIY-friendly one: the Blue Mountains by train. A return Opal fare to Katoomba runs about $19 on a weekday, next to $150 to $200-plus per person for a coach tour covering the same three stops. Spend day one on Sydney’s harbour as a base, not the main event; for the deeper city version of these same two days, see the 2-day Sydney itinerary . Add a day and this plan becomes the 3-day version , which folds in Royal National Park.
Book these before you go
- Check Sydney hotel rates near Central Station on Booking.com; both days on this itinerary start from there.
- Book an all-inclusive Blue Mountains day tour on GetYourGuide if you’d rather skip the DIY train and let someone else drive.
| Day | Focus | Distance / train time | Cost |
|---|---|---|---|
| Day 1 | Sydney harbour: Circular Quay, Opera House exterior, Harbour Bridge walk, Manly ferry | Home base | Ferry $8.39 each way |
| Day 2 | Blue Mountains: Echo Point, Three Sisters, Scenic World | ~2h by train from Central | ~$19 return train + $55 Scenic World pass |
Day 1: Sydney harbour, kept simple
Book a hotel near Central Station rather than Bondi or Manly; day two’s train leaves from there, and every longer version of this itinerary uses the same station. Walk Circular Quay and the Opera House forecourt, free to wander, though the interior needs a paid tour or a performance ticket. Cross the Harbour Bridge on its free pedestrian walkway, then catch the Manly ferry, a flat $8.39 fare each way that covers more harbour scenery than most paid cruises costing twice as much. Keep the evening light; day two starts early.
Day 2: the Blue Mountains, DIY
Trains on the Blue Mountains Line leave Central roughly hourly, and the ride to Katoomba takes about two hours each way on a normal Opal or contactless fare, around $9.55-9.65 one-way. At Katoomba, walk to Echo Point in Blue Mountains National Park for the Three Sisters, then Scenic World for its Railway, Skyway, Cableway and Walkway; the Unlimited Discovery Pass runs about $55 adult, $30 child. Eat in Katoomba town rather than at Scenic World itself, the shops on the main street are cheaper and better. See the full Blue Mountains price rundown for every ticket broken down.
Is the train actually cheaper than a Blue Mountains tour?
Yes, by a wide margin. The DIY train-plus-Scenic-World day costs roughly $74 all in, against $150 to $200-plus per person for a guided coach tour hitting the same three stops. The tour buys commentary and a fixed schedule; the train buys the same views and attractions for under half the price, with one change of plan required along the way, none.
Can I fit Melbourne, Uluru or the Great Barrier Reef into a 2-day trip?
No. All three are flights, not day trips, roughly an hour to Melbourne and about three hours to Uluru or Cairns for the Reef. None of them work from a two-day Sydney base; treat them as a separate trip built around a flight, not an add-on to this one.
Two days buys exactly one day trip, and the Blue Mountains earns the spot: cheapest, easiest to DIY, and the anchor every longer version of this itinerary builds from.
