As the title says, after reading the OneWorld web site, I think I'm eligible to access the Qantas Emerald lounge which I frequent when flying Qantas, but for the first time ever, tonight I'm flying AA73 on AA metal to LAX-SYD. I've read all the exceptions and can't find one that rules this out as it's leaving North America.

I'm ExecPlat/OWE and also have a Business ticket on this route. Looking to confirm that I'll have no issue heading over to TBIT and getting in Qantas Emerald lounge despite my flight being AA. As I have a 7 hour layover, I'm thinking of heading there for majority of the time and then heading to T4 Flagship about an hour before my flight. I want to avoid a walk of shame if I'm denied.
