Singapore-based budget airline Jetstar Asia will close down at the end of July, its Australian owner Qantas has announced.

The closure of Jetstar Asia will not impact its Australia-based Jetstar Airways operations, nor those of Jetstar Japan, according to a statement from Qantas.

"We have seen some of Jetstar Asia's supplier costs increase by up to 200 per cent, which has materially changed its cost base," said Qantas Group Chief Executive Vanessa Hudson in the statement.

Several of Australia's Qantas airline planes have been diverted from London to Paris, with other flights likely to be affected, it said.

Avalon Airport is exclusively served by Jetstar, a budget airline operated by Qantas.
