Cancellation rate is cancellations divided by flights scheduled. On-time rate is on-time departures divided by flights flown, because a flight that was cancelled cannot also have left late. Each direction is counted separately: Sydney to Melbourne and Melbourne to Sydney are different flights with different records.
Which airline is most reliable on Brisbane to Perth
The carriers on this route perform much the same as each other, within 0.1 of a percentage point. Choose on price and timing; the reliability difference is not real enough to pay for.

| Virgin Australia | 0.2% | 69.8% | 1,492 |

The flight home
The return leg is a different flight with a different record: Perth to Brisbane is cancelled 0.5% of the time, more often than the outbound. Morning departures generally do better than evening ones on any route, because a delay early in the day follows the aircraft around for the rest of it.
If it is cancelled
About 11 Brisbane to Perth flights were cancelled over the last twelve months, so on this route it is worth knowing the answer before you are standing at the desk. Australia has no fixed compensation payment like the European one. If the airline caused it you can ask for a refund or a seat on the next flight, on any carrier, and most airlines will cover a meal and a hotel. If it was weather or air traffic control, you get the later flight or your money back and nothing else.
