Update on seating arrangements for F, CL and P1, this is the new system based on feedback from soft opening (and that's one reason why a soft opening is useful, to identify and where possible remedy real-world issues like this).
"The seating area at the furthest end of the lounge, closest to the open kitchen, is nominally set aside for Qantas' first class, Platinum One and Chairman's Lounge passengers. While the tables are not reserved per se, Executive Traveller understands that the maître d' will escort passengers to this 70-seat space based on their travel class or status and, except for the busiest times, guide other travellers (Qantas Platinum and Oneworld Emerald) to other areas of the dining room."
