Each direction is counted separately: Sydney to Melbourne and Melbourne to Sydney are different flights with different records.
Which airline is most reliable on Perth to Karratha
The carriers on this route perform much the same as each other, within 0.3 of a percentage point. Choose on price and timing; the reliability difference is not real enough to pay for.

The flight home

If it is cancelled
About 27 Perth to Karratha 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.
