London was placed second, although it had 24 per cent fewer bookings.

In total 12 Asian cities made the top 20, including Singapore which was up 17 per cent and took fifth spot.

"Aussies are seeking richer experiences for less, which is why we've seen a rise in travel to various destinations in Asia," said senior growth manager Robyn Lee.

"In 2018, we expect to see Aussies continue to explore destinations closer to home so as to reduce travel time and make the most out of their annual holidays and time abroad."

Domestic bookings were up 14 per cent this year.
