No... don't let them know about that please...
Anyway, virtually all (if not all) QF flights leave from the C gates, and the EK lounge is just upstairs from the entry point to those gates. There aren't any other lounges closer to this set of gates. Basically, when you go through immigration, turn left, and walk all the way to the end before you have to turn. This is where the escalator is to go up. Once up the escalators, you'll see the Rainforest lounge straight ahead. Take a hard left, and the EK lounge is on the left. There are not many signs around that would point you to the EK lounge so it's not as easy to find as it should be, but you can also follow the signs to the Rainforest lounge, which I find to be a little bit more prominent. Also, once you're past the entrance of the lounge, that part looks quite boring. However, go through there and follow it around to the left, and you shall find views of the runway. The food is a little further along.
Overall, I think the QF lounge will appeal more to those who prefer something with a more modern style, while the EK lounge is more of a traditional seat back, relax, and be really comfortable type of place.
