I used the kerbside check in two weekends ago in MEL for a J flight to AKL. I honestly thought that this was the Emerald, WP, First check in that QF are supposed to have anyway re. the oneworld agreement. There is no other Emerald/F check in once inside the main hall.
The GF was amazed at the spa and got a 45 minute treatment. I, on the other hand sampled then re-sampled the excellent champagne on offer. We arrived 1:45min before boarding and the lounge was pretty empty. I note that the spa wasn't offered and I had to ask. Maybe only F pax get offered the spa with clued in WP's getting the next best slots?
I think djsflynn may have the best idea if you have the flexibility.
Even if the OP misses the spa he will still start his trip in great style.
