A record-breaking one million international passengers passed through Melbourne Airport in December, with growing demand from Chinese tourists helping to boost numbers.

It’s the first time the airport has cracked one million international passengers in a single calendar month, surpassing the previous record of 977,938 in January 2017.

The launch of three new non-stop services to Vancouver and Chinese cities Zhengzhou and Hangzhou in December contributed to the boost, CEO Lyell Strambi said on Wednesday.

‘December was an outstanding month with great passenger numbers that reflect the demand for international travel in and out of the world’s most liveable city,’ Mr Strambi said.

Terminal Two also had its busiest day on record on December 23, with 38,716 international travellers rushing through arrivals and departures prior to Christmas.
