If you want the single cheapest ticket price, it is SkyBus at $24.60 one way. That is the quick answer.
But the cheapest overall option depends on where you are starting from, how many people are traveling, and how much time you can spare. A taxi split between three or four people often beats SkyBus on cost per person and saves a lot of time.
This guide compares every budget option so you can pick the true cheapest choice for your trip.
Quick comparison
| Option | Typical cost (to airport) | Best for | Main drawback |
|---|---|---|---|
| SkyBus | $24.60 per person | Solo travelers from the CBD | Only goes to Southern Cross Station |
| Public transport | $5 to $10 | Extreme budget only | Multiple connections and long travel time |
| Shared shuttle | $15 to $25 per person | Solo travelers who want pickup | Slow and fixed pickup windows |
| Fixed-price taxi | $38 to $170 total | Groups of 3 or more | Higher cost for solo travelers |
| Ride share | $50 to $120 total | Occasional off peak deals | Surge pricing and uncertainty |
Option 1: SkyBus
Price: $24.60 one way, about $40 return
Route: Southern Cross Station only. If you are not staying near Southern Cross, you will need a tram, train, or taxi connection.
Best for:
- Solo travelers
- CBD hotels near Southern Cross or the free tram zone
- Light luggage
Not ideal for:
- Groups of three or more
- Suburbs outside the CBD
- Very early or late flights (check schedules)
SkyBus is the lowest ticket price, but not always the lowest total cost if you need a paid connection.
Option 2: Public transport
There is no direct train to Melbourne Airport. The closest you can get is a mix of trains and buses. It is cheap on paper, but slow and inconvenient with luggage.
Reality check: Unless you live along the limited bus routes near the airport, this option is usually not worth the extra time and hassle.
Option 3: Shared shuttle
Shared shuttles can be cheap per person and include pickup, but they add time because the van makes multiple stops.
Pros:
- Door to door pickup
- Good for solo travelers on a budget
Cons:
- Fixed pickup windows
- Multiple stops and long travel times
Option 4: Fixed-price taxi
This is the best value for groups. A fixed-price fare is a single price for the entire vehicle, so the cost per person drops fast as your group size increases.
Group math to the CBD:
- 1 person: SkyBus $24.60 vs taxi $82
- 2 people: SkyBus $49.20 vs taxi $82
- 3 people: SkyBus $73.80 vs taxi $82 (taxi wins)
- 4 people: SkyBus $98.40 vs taxi $82 (taxi is cheaper)
Bottom line: If you have three or more people, a taxi is often the cheapest per person and it is door to door.

Option 5: Ride share
Uber and DiDi prices can be competitive during quiet periods, but they are unpredictable at the airport due to demand surges.
If you see a low price in the app, it might be worth it. If there is surge pricing, a fixed-price taxi is usually the safer bet.
When the cheapest option changes
Scenario 1: Solo traveler from the CBD
- SkyBus: $24.60
- Taxi: $82
SkyBus is clearly the cheapest.
Scenario 2: Family of four from Doncaster
- SkyBus tickets: $98.40 plus travel to Southern Cross
- Taxi: about $110 door to door
The taxi is cheaper and faster.
Scenario 3: Three friends from Brunswick
- SkyBus tickets: $73.80
- Taxi: $71
Taxi is equal or cheaper, and saves time.
How to choose the true cheapest option
Use these simple rules:
- Solo, CBD, light luggage: SkyBus
