In the Sydney airport international terminal does Cathay Pacific have its own lounge or does it use the Qantas lounge? If it has it's own lounge is it better than the Qantas Business Lounge? I am Marco Polo Gold (OW Sapphire) and want to be sure to choose the best option when flying Qantas econumy class to Manila later this year.

Cathay doesn't have it own lounge, but like all Oneworld airlines in Sydney shares the Qantas lounges – and yeah, as a Marco Polo Gold you're entitled to use the Qantas International Business Lounge.
