420 Bus to Sydney Airport — The Levy-Free Alternative
Most guides to getting to Sydney Airport by public transport start and end at the train. Pay the station levy, change at Central or Wolli Creek, arrive having spent $20 on the privilege. There is a cheaper, more direct option — but it is one most Sydneysiders who do not live near its route have never heard of.
The 420 bus runs from Westfield Burwood all the way to both airport terminals, stopping at Campsie, Bexley North, Rockdale and Banksia along the way. No station levy. No transfer required. Just a regular Opal tap-on, tap-off fare — around $3 to $4 depending where you board. The catch is it is not for everyone, and there are a few things worth knowing before you decide it is your option.
The service is run by Transit Systems on behalf of Transport for NSW, runs around the clock every day of the week, and is shown in full on the official 420 timetable (PDF). Here is the honest picture of who it suits and who it does not.
What the 420 bus actually does
The 420 starts at Mascot Station, collects passengers at the Domestic Terminal (T3) first, then the International Terminal (T1), before heading north through Arncliffe, Rockdale, Banksia, Bexley North, Clemton Park and Campsie, and finishing at Westfield Burwood. In the other direction it runs Burwood to Mascot, stopping at the International Terminal first and the Domestic Terminal second.
The full trip from Burwood to the International Terminal takes around 32 minutes on a good daytime run. To the Domestic Terminal it is closer to 43 minutes. The service runs every 10 to 15 minutes during the day and operates around the clock on all days including weekends and public holidays — the last service from Burwood departs just before midnight, with overnight runs at 12:48am, 1:48am and 2:48am.
The fare is a standard Opal card fare — roughly $3 to $4 depending on your boarding point and time of day. Compare that to the airport train, which adds a $17.92 station access fee per person on top of your normal fare. For two people making a return trip, that levy alone adds up to over $70.
Journey times from each suburb — using real timetable data
These times are drawn from the official June 2026 timetable. They are typical daytime Monday to Friday runs — allow a few extra minutes during peak hour (roughly 7am to 9am and 4pm to 6pm) when the bus can run slightly behind schedule.
| Board at | To T1 International | To T3 Domestic | Train alternative | Verdict |
|---|---|---|---|---|
| Mascot Station | ~11 min | ~6 min (T3 first) | Direct Airport Link — but pay $17.92 levy | Bus — saves the levy, nearly as fast |
| Burwood | ~32 min | ~43 min | ~26 min via Central, but pay levy + 1 change | Bus — comparable time, saves levy |
| Campsie | ~22 min | ~33 min | Metro to Sydenham, T8 to airport (~40+ min, pay levy) | Bus — clearly faster and cheaper |
| Bexley North | ~15 min | ~26 min | No direct train — bus or drive to Rockdale first | Bus — only practical public option |
| Rockdale | ~8 min | ~19 min | T4 to Wolli Creek, change to T8 (~18 min, pay levy) | Close — bus saves levy, train is similar time |
| Banksia | ~5 min | ~15 min | T4 to Wolli Creek, change to T8 (~15 min, pay levy) | Close — but bus still saves $17.92 per person |
If you are travelling from Mascot
This is my own situation. I typically head to the airport from Mascot rather than the Inner West, and the 420 makes sense here in a way that is easy to overlook.
The bus departs Mascot Station, stops at T3 Domestic (around 6 minutes), then T1 International (around 11 minutes). That is a straightforward ride with no change and no levy — much the same time as the Airport Link train but without paying $17.92 on top. For one person it is a reasonable saving. For two people travelling together it is $35.84 saved for doing nothing different except tapping on a bus instead of a train.
The Mascot Station bus stop for the 420 is on Bourke St. Scan the QR code to find when the next bus leaves.
The return trip — where people come unstuck
Getting to the airport on the 420 is easy. Getting from it is where you need to pay attention.
Arriving at T1 International, the 420 toward Rockdale, Campsie and Burwood departs from the upper level kerbside stop outside departures. The bus continues in the same general direction it was already heading — north, toward Mascot and then Burwood. That sounds logical but the stop signage is easy to confuse with services heading south toward Botany. After a long flight, when you are tired and your phone is at 12%, it is worth being deliberate about checking the destination board on the bus before boarding.
Who this bus suits — and who it does not
The 420 is a regular Sydney city bus, not a dedicated airport coach. That changes a few things worth flagging.
Hand luggage or one small bag: This is the sweet spot. If you are travelling carry-on only, the 420 is excellent — fast, cheap, frequent, no fuss.
One mid-size checked bag: Manageable. There is a small storage area behind the driver’s cab that fits a mid-size bag without blocking the aisle. Worth using — most passengers do not know it is there.
Two large suitcases: This is where it gets uncomfortable. Sydney buses have no underfloor storage or luggage racks. You are managing bags in the aisle at every stop. At this point the train, a cab or a rideshare starts to make more sense.
Travelling with a pram or wheelchair: The 420 is wheelchair accessible with low-floor entry and priority flip-up seating at the front. The bus will accommodate you — but a crowded peak-hour service with a pram can be genuinely awkward. Check the live crowding information on the Opal app before boarding if timing is flexible.
Peak hour: The 420 can get crowded, particularly the Rockdale-to-airport section on weekday mornings. If you are catching a 7am flight from Campsie with luggage, factor in that you may be standing.
How Campsie passengers get to the airport — and why the bus wins
With the Bankstown due to open in 2026 (?) Campsie will be on the Metro network. To reach the airport by train from Campsie, you would take the Metro into the city — most likely to Sydenham — then transfer to the T8 Airport & South Line. It works, but it involves a transfer and the full $17.92 station levy on top of the fare. The whole journey runs to 40 minutes or more.
The 420 bus from Campsie Station (Beamish Street) reaches the International Terminal in around 22 minutes with no transfer, no Metro-to-train changeover, and no levy. For Campsie residents, this is not a close call.
Rockdale and Banksia — where the train becomes a genuine option
Rockdale and Banksia are both on the T4 Eastern Suburbs & Illawarra Line. From either station, a train to Wolli Creek with a change to the T8 Airport Link reaches the International Terminal in around 15 to 18 minutes — comparable to the 420 on time.
The difference is the $17.92 levy. If you are travelling solo and comfort matters more than $18, the train might win. If you are travelling as a couple, that is $35.84 in levies each way — and the bus suddenly looks very attractive even when the time difference is minimal.

Frequently Asked Questions
Yes. The 420 serves both Terminal 1 International and Terminal 3 Domestic. Travelling from Burwood, it stops at T1 International first, then T3 Domestic. Travelling from Mascot Station toward Burwood, it picks up at T3 Domestic first, then T1. If you are flying with Virgin Australia or Jetstar (T2), alight at the T3 stop — the terminals are a short walk apart.
A standard Opal card fare — roughly $3 to $4 depending on your boarding point and time of day. Off-peak travel (before 7am, after 7pm on weekdays, and all day on weekends) attracts a discount. Crucially, there is no airport station access levy on the bus. That levy ($17.92 per person each way in 2026) applies only to the underground train stations inside the airport precinct.
Every 10 to 15 minutes during the day. The service runs around the clock every day of the week including public holidays, with overnight services from Burwood at approximately 12:48am, 1:48am and 2:48am. Check the official timetable (PDF) for exact times on your travel day.
The 420 bus from Campsie Station on Beamish Street is the most direct and cheapest option. It takes around 22 minutes to the International Terminal with no transfer required. The Metro-to-train alternative requires a change at Sydenham, adds the $17.92 airport station levy, and typically takes longer. For most Campsie passengers, the 420 is clearly the better option.
Two realistic options. The 420 bus from Rockdale Station on Railway Street takes around 8 minutes to T1 International and runs frequently. Alternatively, the T4 train to Wolli Creek with a change to the T8 Airport Link takes around 15 to 18 minutes but adds the $17.92 station levy. Time-wise they are comparable — the bus wins on cost, particularly for couples or groups.
The 420 bus departs from Mascot Station on Coward Street and reaches T3 Domestic in around 6 minutes and T1 International in around 11 minutes. It runs frequently throughout the day and overnight. The Airport Link train from Mascot is faster on paper but adds the $17.92 station levy — for the small time saving, the bus is usually the better value option.
Sydney buses have no underfloor storage or luggage racks. There is a small storage area behind the driver’s cab that fits a mid-size bag without blocking the aisle — worth using if you have one bag. If you are travelling with two large checked suitcases, the train or a rideshare will be more comfortable. The 420 is best suited to carry-on travellers or those with one manageable bag.
The airport station access fee ($17.92 per person in 2026) applies to journeys that use the underground train stations inside the Sydney Airport precinct — International Airport Station and Domestic Airport Station. The 420 bus drops you at street-level kerbside stops outside the terminals. It does not use the airport train stations, so no levy applies.
The 420 stops outside Terminal 1 on the upper departures level kerbside. For the return journey from the airport toward Rockdale, Campsie and Burwood, the stop is also on the upper level — check the destination board on the bus carefully before boarding, as other services depart from nearby stops heading in different directions.
Yes. The 420 runs around the clock every day of the week. Overnight services from Westfield Burwood depart at approximately 11:48pm, 12:48am, 1:48am and 2:48am. Early morning services from Burwood begin at 4:41am on weekdays and 4:26am on Saturdays. This makes it one of the few public transport options for very early morning or late-night flights — always check the official timetable to confirm exact times.
