Australia's Sydney Airport served 2.99 million passengers in May, a 3.1% rise compared with the same period in 2013.
The rise in passenger traffic can be primarily attributed to the growth in Chinese passengers, which increased by 11.4% during the month.
Domestic traffic at the airport reached 2.02 million passengers, marking an increase of 2.1%, while international traffic grew by 5.6% to 973,000 passengers.
Sydney Airport CEO Kerrie Mather said: "We delivered a strong passenger performance during May.
"The result was primarily driven by strong inbound demand with our foreign nationalities."
The airport noted that Philippine outbound tourism has more than doubled over the last eight years with nearly 2.5 million Filipino tourists a year, making it an attractive market for Sydney to expand its partnership with Cebu Pacific.
Mather added: "As our fourth long-haul low-cost carrier, Cebu Pacific Air will operate Sydney to Manila services four times weekly from 9 September, later increasing to five flights a week to coincide with the peak holiday season.
"Low-cost carriers such as Cebu Pacific Air are increasingly popular with Australian travellers and this new service will provide more choice and value for passengers travelling to and from the Philippines."
