Can I use the Sydney International 1st Lounge on transit from Singapore to New Zealand?

I’m booked on 1st flex fare from Singapore to New Zealand. Singapore to Sydney is in 1st. But Sydney to New Zealand tops out at Business. Can I use the Sydney International 1st Lounge while on transit in Sydney? Grateful for advice/experience as I am unable to find any definitive information on the Qantas website and online. Thanks.

If you have oneworld emerald then yes.

Thanks. Yes, the Qantas website is clear on lounge access with OneWorld (or Qantas) status. Unfortunately, I don’t have status :-)

You'll have access by virtue of connecting from long haul F:

Connecting between oneworld marketed and operated flights:

• First and Business Class customers connecting on the same day of travel, or before 6am the following day, can access the lounge when travelling between an international long haul (a oneworld international long haul flight is defined as an international flight marketed and operated by any oneworld carrier with a scheduled flight time longer than 5 hours) and an international short haul or domestic flight (and vice-versa).
• Lounge access will be determined on the international long haul ticketed flight (either First of Business Class) regardless of the ticketed class of travel on the international short haul or domestic flight.

Thanks very much Happy Trails!
