First Time First Class Flyer

Hi all,
I have booked first class with Qantas on Emirates A380 SYD - AKL and, being my first time in both first class and on a codeshare flight I was after some advice.  I do know I get access to the Qantas First Lounge at Sydney airport.
As I booked through QF will they call me the day before to potentially book a spa treatment?
Any suggestions to maximise my short flight time?
Can I check-in early through the Qantas First check-in or only through Emirates (which means 3 hours prior to take-off).

Thanks :)

Because the flight is still operated by EK, the QF First Host service won't be available as that service is only available to F passengers on QF operated flights.

QF1st Class lounge at SYD is actually outsourced and operated by a hotel chain. and not very well, I might add. 

OP, when are you flying SYD - AKL.
The reason I ask, is that in a few months, there won't be a SYD - AKL EK 380 anymore.
If you are flying soon, good, but if you are flying after Jul/Aug/Sep, you might find yourself relegated to the QF 330 in J, or have to reroute via MEL or BNE to AKL, or go SYD - CHC with EK F, and then JQ NZd CHC - AKL.

The QF SYDi F lounge is one of the best, I have done the EK SYD combo J and F lounge too, spend a bit less time in the QF SYDi F lounge, so you can also get some time in the EK SYD lounge too.
I have done them both, also have done the QF SYDi J lounge, the F is the better than that, you do get good views.
Its quite large inside the secure part of SYDi airport and the EK lounge is closer to the gate, so give it some time.
I believe the QF SYDi F lounge opens at 6am, the airport's immi and security opens about 4.30am or so.
If you live in SYD, I would aim to leave home by Uber at 3am, gives you time to get to SYD airport, and then to get through immi and security.
If you don't live in SYD, and have the option, I would if I were you stay the night at the Rydges Sydney Airport, I have done it, right across from the int terminal.
Sometimes the Express path bunting will still lead you to the general immi line, smartgate is good, easy to use.
You drop off your OPC (outgoing pax card) into a clear lidded box these days.
You put your photo page of passport down onto plate glass, no need to push it in too deep, look slightly to the right, you hear a short beep, and the gate opens.
They don't stamp passports anymore, entering NZ is just light leaving Aust, immi wise.  No small paper ticket on entry to NZ anymore (which Aust still has on entry).
You just show NZ IPC (incoming pax card) at the downstairs customs zone, they ask a few questions, might xray your bags, or not, and then you are free onto the open zone.
I like the AKL Skybus, a bit pricey though, (granted you might have someone to pick you up).
I have also done EK AKL lounge, its like the SYD one, good food, serve yourself grog, shows, large bank of computers in an alcove.
Enjoy the trip.

You will enjoy EK F on SYD - AKL - but be aware that they do not provide the same service level as they do on other sectors (i.e.DXB BCN) where the wine list and food offerings are definitely better.

I agree f lounge is excellent. Forget the spa unless on QF flight in f. I've never been able to access when on EK. On board try to board first and then proactively request your preferred shower time. Seat 2a is my preferred. On wine list middle wine ie number 3 of 5 is usually the special and often a better bet than the others. 2 months ago they were serving Astralis at over $500 retail!! Paradis cognac is great and they will serve it to you at the bar if u ask!

Thanks everyone for the advice.  Greatly appreciated.

I guess my time in either lounge will be restricted by only  being able to check-in 3 hours before departure even in first class.

Shame since 'online checkin' really doesn't mean much when travelling o/s.

BTW 2A was my choice as well :)

Passed through Auckland Airport the other week and immigration was a breeze with electronic gates for those passports which can be electronically read. Baggage delivery prompt and customers bearable, even with having to have all incoming baggage x-rayed. If time is not of the essence too, Auckland duty free booze is both cheap and generous in its allowances, especially for spirits. It also saves you lugging it onto the plane. No wash bags or limo offered by EK on this route and on a flight two weeks ago in business class, the wine list was very poor. The crew had also each been given iPhones/pods, which they used to both look things up and take food orders. This actually appeared to slow the service down somewhat and make it less personal. Their knowledge of the wines was not great either. The bar at the back is definitely worth a visit, though lacks the premium variety of booze found in the somewhat soulless bar at the front of first class.
