I'm flying LGW-PVG on China Eastern in economy, landing 7.30am in T1. I then fly to Sydney on QF130 in business about 12 hours later. I'm planning to find a nearby hotel to rest up in (I'll be landing at about midnight UK so it works nicely) but I'm also curious about lounge options. The wiki at the top seems to suggest I should be using a T2 lounge for Qantas but I think that's out of date?

As best I can tell the only option is the China Eastern lounge. I'm guessing I can't use the first class China Eastern lounge as it's not a OW lounge so my OW Emerald status has no value, and will instead be using the seemingly very much shoddier business class China Eastern lounge courtesy of my flying in business. Can anyone confirm that's the lounge I need to use?

Many thanks in advance!
