In terms of actual numbers, Australian flyers leaving the country led the way, with an 11 per cent increase. For those coming into Sydney, the number of Chinese visitors rose by 20 per cent and Canadian, German and French visitors also showing double-digit growth.
The number of Korean and Japanese visitors dropped significantly, by 13 per cent and 7 per cent respectively.
The health of the aviation industry was further underlined by a 6.7 per cent rise in the number of passengers who flew with Air New Zealand last month, with its long-haul services rising sharply thanks, in part, to Kiwi fans travelling to Paris for the Rugby World Cup.
The latest overall increase comes as Sydney prepares for the arrival next week of the new superjumbo, the double-decker Airbus A380, the first of which is to be operated by Singapore Airlines.
Figures indicated that the growth in overseas traffic shows no sign of abating, supporting the contention of airlines such as Qantas and operators like Macquarie Airports that passenger numbers and profits will be well up over the next financial year.
