China Southern will deploy an A380 on one of its two daily services between Guangzhou and Sydney from next month.
The superjumbo will cover Australia's peak summer season, from December 5 until February 28.
It will replace the A330 currently serving flights CZ325 and CZ326. Flight times will remain unchanged, with Qantas continuing to be a codeshare partner with codes QF327 and QF328 respectively.
China Southern's A380 comes in a three-class configuration, with eight seats in first class, 70 in business and 428 in economy.
It's worth noting that China Southern had previously deployed the A380 on the Guangzhou to Sydney route, but was forced to replace it with the much smaller A330 back in February due to poor passenger loads.
The carrier already offers more flights from China to Australia than any other airline, but the addition of the superjumbo will boost capacity by about 50 per cent.
China Southern has been working hard to boost travel between its home country and Australia. Just last week, the airline announced that it would work with Tourism Australia to invest a further AU$4.2 million (£2.3 million) in advertising Down Under as a destination.
