- Your destination city in Australia
- Whether your flight is direct or includes stopovers
- The airline you choose

- The length of your layover
Generally speaking, most travellers flying from London Heathrow to major Australian cities like Sydney, Melbourne, Brisbane, Perth, or Adelaide will spend at least 20 hours travelling when stopovers are included.
