Alright, let’s talk about figuring out the distance between Sydney and Melbourne. I actually had to look this up recently because I was thinking about a trip.

So, the first thing I did was just try and guess. You know, you kinda picture the map of Australia in your head. Sydney’s up there, Melbourne’s down there, pretty far apart. But guessing doesn’t really help with planning, does it?
Naturally, the next step was grabbing my phone. I just opened up a browser and typed in something simple, like “how far sydney to melbourne”. Pretty straightforward.
What I Found Out
Okay, so the search results immediately gave me a couple of numbers, which makes sense because it depends on how you’re travelling.
- Driving: This was the main one I saw. Most places said it’s roughly around 870 to 900 kilometres by road. That’s mostly sticking to the main route, the Hume Highway. It also mentioned driving time, usually something like 9 to 10 hours if you’re driving straight through, but realistically, you gotta add time for stops, traffic near the cities, maybe roadworks.
- Flying: Then there’s the “as the crow flies” distance, which is basically the straight line path planes take. That’s shorter, somewhere around 700 to 720 kilometres. Obviously, flying is way quicker – the flight itself is only about an hour and a half. But then you have to remember getting to the airport, checking in, security, waiting, and getting from the destination airport into the city. So the total travel time is longer than just the flight.
Putting it Together
So, when someone asks “how far?”, the answer isn’t just one number.
If you’re planning a road trip, you’re looking at that 870+ km figure and a good solid day of driving. You need to plan where you’ll stop for fuel, food, maybe even an overnight stay if you want to break it up.

If you’re thinking of flying, the distance number itself (around 715 km) isn’t as important as the flight time and the total door-to-door time, which could easily be 4-5 hours all up.
So yeah, that was my process. Started with a vague idea, did a quick search, and found out there are different answers depending on whether you’re hitting the road or taking to the skies. For practical purposes, knowing the driving distance and estimated time was most useful for my initial thought process about a potential road trip.
