I find it very strange that as VS gold, you can go in the VS lounge when not even flying VS though. So shorthauls off to Paris with one of the best business class lounges in the world.

To be fair. CX J and F are pretty damn good. I think it was back when only BA and AA J lounges were open, that I really pined for the VS one.

This is not my experience at T3 (as a BA GCH). From memory the "children don't count" rule applies to Qantas Frequent Flyers but not OneWorld partners.

I agree with this. That was definitely my experience at TBIT at LAX as well where I tried to guest my g/f and our 17 year old daughter into the First Class lounge there. The chap at the podium was having none of it and showed me the computer screen where it clearly stated one guest only.

LHR is detailed here https://www.qantas.com/travel/airlin...egory=qcLounge and it specifically states only one guest (irrespective of whether you're a Qantas or OW member) whereas if you look at LAX which is here https://www.qantas.com/travel/airlin...egory=qcLounge it allows one guest if you're entering as a OW member, but if you're a Qantas member then you're allowed one guest plus up to two children aged between 4 and 17.

So I definitely don't think it's as clear cut as others have alluded to.

Try this before anything else.
Hopping about is fun for some people but it isn't properly selling the 'how the other half live' idea. A nice leisurely sojourn in T3 CX definitely is.

Sorry, a bit OT
 

Qantas T3 is now selling access for £55 for extra guests.

I'd say it would be more Qantas level of lounge. They don't serve champers normally in most of the AMEX lounges (unless you are Centurion cardholder), so it's arguable whether BA Club is better if you rugby tackle a server to get champers. Food is usually of a level of a Priority Pass lounge circa 2014 (a lot of PP lounges have impressed me in recent times if you can get in them). I speak only from experience of the LAS AMEX lounge, which is much better than the PP one there.

I think they are unlikely to get past the dragon guarding the door.

Friends of mine who lounge hop at T3 regularly have a rule: "Drink at Qantas, eat at Cathay."

Apart from a prior comment about lounge dragons not letting you in, I think there are additional problems:

You will probably get your chicken through The First Wing but the Second Wing, the Beak Wing and The Breast Wing may refuse.
BA have a strict policy of only one emotional support animal allowed - but you can get by this by saying that the fox is actually a family member (under 18, if that helps at Qantas).
As you pass the horses in the F lounge cover your fox's eyes - horrible flashbacks about prior hunts may occur.
Don't let your chicken anywhere near the buffets if chicken dishes are available - loud screams of "Mama".
You may be stopped at security - grain in sufficient quantities and in the right conditions can be explosive.
You will fall foul (!) of the BA rule on maximum two items of hand baggage, unless you eat the grain beforehand. Ditto the chicken, and God forbid, the fox.
Next time book an HBO fare: Hares, Birds and Oats.
If you are CE - either the chicken or the fox will need to be seated apart - check with your fellow travellers if they have any preference. ("I was seated next to this real fox the other day").
You will not be allowed in an Emergency Exit row, the fox will have difficulties opening the window and the chicken may misunderstand "Evacuate, evacuate."

Otherwise Happy Trails!
