I am flying QF from lAX to SYd but want to use the KE lounge .

Both from Tom Bradley terminal but as they depart from opposite piers is it possible to access the lounge once you are through security or do you need to clear security for the QF side and seperately for the KE side .

I guess what I am asking is it poss to pass from one pier to the other in Tom bradley easliy

Thanks
