I tapped off at Circular Quay one Saturday after a run over to Taronga and back and the number on the reader wasn't the one I had in my head. It was only a couple of dollars out, so I stood on the concourse for a bit trying to work out where the extra had come from. Sydney ferry Opal fares run on the same tap on and tap off logic as everything else, so your price comes off the distance between the two taps and it lands when you tap off rather than when you step aboard. That part's simple enough and the harbour is where it picks up wrinkles.
The answer took me longer to find than it should have. Ferries have their own fare table, separate from the metro, bus and light rail ones. The off peak discount doesn't touch them at all, which surprises nearly everyone I mention it to. And some of the boats pulling into the pontoon next to yours are charged on a basis that has very little to do with Opal, even when you pay with the same card.
How Sydney ferry Opal fares are actually worked out
Every Opal mode charges by the distance between where you tap on and where you tap off and each mode carries its own set of bands. The ferry table isn't the metro table with a boat drawn on it. It's the simplest one on the network though, because ferries only get two distance bands, one for trips up to 9 km and one for anything past that. There's no off peak column on it at all.
I'm not printing the band prices here, because these get reviewed most years and a stale number does more harm than no number. The adult Opal fares page has the live ones under the Ferry fares heading and it opens in a couple of seconds.
Does the off peak discount change the Opal ferry cost?
No. This is the one that catches people out more than anything. Since the off peak discount came in a lot of us have quietly assumed every fare outside the busy hours is thirty per cent cheaper. The Transport for NSW peak and off peak page names metro, train, intercity, bus and light rail as the modes it covers. Ferries aren't on that list. So a crossing at half past eight on a Tuesday night costs exactly what the same crossing cost that morning. The boat is the one mode where waiting out the peak buys you nothing at all.
The caps are where a harbour habit stops costing more
Caps are the reason a ferry commute is cheaper than the per trip price makes it look. Once the day's travel adds up to the cap the rest of that day rides free and the week works the same way. As of July 2026 the Transport for NSW Opal benefits page puts the adult daily cap at $19.30 from Monday to Thursday and $9.65 on Fridays, Saturdays, Sundays and public holidays, with the weekly cap at $50. Concession, child and Gold Opal caps are all lower again and they're on that same page. Those numbers get reviewed most years, so treat them as where things stood when I wrote this.
What is the ferry fare cap in Sydney?
There's no ferry only cap. The cap is a whole of network number covering everything you tap on that day, so your ferries, buses, trains and light rail all count towards the same total. That's genuinely good news for a harbour commute! The ferry leg is usually the dearest single tap in your day, so it does most of the work getting you up to the cap and a fair bit of what you catch afterwards ends up costing you nothing.
Two boats to the same wharf can be charged completely differently
Three different things can happen when you tap on at a harbour wharf and only one of them counts towards your cap.
- A normal Opal fare. The Sydney Ferries F routes charge a standard Opal fare with the standard Opal benefits behind it, caps included.
- OpalPay. Selected private ferries let you pay using an Opal card through OpalPay. SeaLink/Captain Cook Cruises are on it and so are My Fast Ferry's routes other than Manly to Circular Quay. The card works. The fare doesn't behave like an Opal fare.
- The operator's own ticket. Smaller private services and the harbour cruises want a ticket bought from them and won't read your card at all.
The middle one is the trap and Transport for NSW says so plainly on the OpalPay page. OpalPay fares are different to standard Opal fares. OpalPay trips don't count towards Opal travel benefits including the daily, weekly and Friday to Sunday caps, transfer discounts or Trip Advantage. So you can tap the same card at the same wharf, get aboard with no fuss and have that trip sit entirely outside the running total you've been building all week. Once a month you'd never notice it. If it's your commute you're paying full freight on ten crossings a fortnight and not one of them counts towards the cap.
Is the Manly Fast Ferry an Opal fare?
On the Manly to Circular Quay run, mostly yes. This is the one thing in here I'd check against your own account rather than take my word for. Manly Fast Ferry trades as My Fast Ferry now and its own site says that service is the same single journey price as the F1 with the same Opal benefits behind it. Transport for NSW is less generous about it. The ferry payments page still lists My Fast Ferry as a private operator you tap on a device as you board and says flatly that full Opal travel benefits are only available on Sydney Ferries. I couldn't get those two to agree in July 2026, so you're getting both. Catch it and read the trip back in the Opal app before you plan a week's budget around it.
What isn't in doubt is My Fast Ferry's other routes. They're OpalPay, so none of them count towards your cap. If you're sorting out which pontoon you want in the first place, I've written up which Circular Quay wharf your ferry leaves from separately.
Two Opal benefits do most of the work on the water
Hardly anybody uses either of these on purpose and both of them are just sitting there waiting.
The first is Trip Advantage. Several trips on the same mode within sixty minutes of your last tap off count as one journey on one fare. The ferries get a special case written into it. On the Sydney Ferries Manly service that window stretches to 130 minutes from tap on and it's the only exception in the whole rule.
The second is the transfer discount. Switch between modes within sixty minutes and the adult fare drops by $2 as of July 2026, which on a ferry plus bus commute adds up to proper money across a fortnight. It applies whether you tap an Opal card or a contactless one. It doesn't apply to OpalPay either, same as the caps.
What is the cheapest Sydney harbour ferry trip you can take?
The Manly return. Nothing else out there gets close. Tap on at Circular Quay, cross, walk the Corso, get an ice cream and get back aboard inside the 130 minutes and the whole afternoon is one fare. That's a full harbour crossing each way for the price of one, which I reckon is the best value trip in Sydney!
Does a return trip to Manly count as one fare?
On the Sydney Ferries service, within 130 minutes of tapping on, yes. Outside it you're paying two fares. It's the one Opal rule I'd genuinely plan a Saturday around, because 130 minutes is two hours ten, so the boat you catch at two hours fifteen is a second fare on a trip you were making anyway.
I go looking for OpalPay trips in my Opal activity now, because those are the ones sitting outside every benefit I've got. It's also where you find the day your normal week hits the cap. Everything you tap after that day is free.
Which leads to the one habit worth building out of all this. Once you know which day of the week your normal travel tips you over the cap, push the trips you were making anyway onto the back half of it. A harbour crossing on a Thursday afternoon can end up costing you nothing at all. The only figure in here I'd still hold up against your own account is that fast ferry fare, because nobody would tell me the same thing about it twice. Get the caps working for you!
