The only oneworld relevance is the "connecting flights" rule which would imply access, although the Qantas Lounge staff sometimes are a rule unto themselves.
It would not hurt to try however, should you go the red-eye route.
Yes it's a OW policy, it's in both the Status access and Business / First access rules:

This is the posted rules for status members:
Emerald and Sapphire members may invite one guest to join them in the lounge. The guest must also be travelling on a flight operated and marketed by a oneworld carrier. You must be prepared to show your boarding pass and frequent flyer membership card, with oneworld Emerald or Sapphire tier status, to access a lounge. Access is available on the day of travel (or before 06:00am the following day), at the airport from which the oneworld flight on which the eligible customer is travelling departs.
If the OP's status was from a non-North American carrier then they would get access regardless on a domestic ticket, however for AA and AS status members, it's only for same day international or before 6am the following day, which doesn't work for the redeye. AA FL was more generous with me when I had that same connection last year (to the AA metal flight, not the JL flight) but the QF lounge was an absolute flat No Way Jose!, bye bye Mr. AA status member. (They have a pretty clear disdain for AA status people).
But the OP said they aren't a fan of the LAX and DFW Flagship Lounges. Unfortunately on that flight with AA status that's the only option (hopefully). But honestly I find both of them to be perfectly fine. They're better than a lot of other OW hub lounges around the world. Definitely better than RJ in AMM, and BA's business lounges at LHR, I'd say a toss up with BA's F lounge, I'd also say better than JL's J and F lounges, I think JL lacks in food selection even in the F lounge and definitely doesn't have the wide array of alcohol that the AA FL's have. I was also a *A flyer for many years and there aren't any *G lounges that are as good as the AA FL's, not even the TK one that everyone raved about. Some of the LH / LX Senator Lounges are on par for liquor but definitely not even close for food, so I do wonder what the metric is for disliking the LAX and DFW FL? It's one of the areas that I actually think AA does a pretty good job.
