OK an update for the thread:
I got to the kerbside F check-in just before 1.30 and presented my printed BP. There was no problem with it, they gave me an express departure card (this gives you express lane access for both security screening and immigration, ie turning right once it becomes "passengers only", you now scan your BP instead of the guard checking it - this is what serfty was referring to in a previous post, I didn't quite get it then

) and a host escorted me just short of immigration as I mentioned it was my first time to the F lounge. I guess I didn't need it as the signs are quite clear but it was nice of them to do so. She also told me that the F lounge closes when QF133 boards at 5.30 as there are no other QF operated flights departing after that. For those going to Nadi on the QF395 codeshare with FJ, that would suck not being able to access the F lounge
Anyway, for some reason I thought the F check-in had a dedicated secret security lane that was out of public sight in some secret tunnel

They had to open the flight for me as I was the first to "check in" even though I had HLO. Went to the express security line and when I got to immigration the express line had 5 or so people so I ducked under the rope into the normal line and got through quicker. Kept the express pass which I will give to Mum when I see her next week (happy belated Mother's day)

.
Got to the lounge just before 1.45 and on scanning the BP they again had to open the flight because if they didn't there would be "some issue at the gate". Went to the spa, all spots were full but they offered to put me on a waiting list in case someone didn't show up. I kindly agreed and then went to enjoy some lovely F lounge food and drink

(will post the menu in another thread). Whilst dining, one of the spa attendants came up to me to inform me that they were still booked up but would let me know in case there was a free spot. In the end there wasn't (no love lost) and when I went for a shower at just before 4.30, I saw that the spa was closed. So it looks like the spa is only open when there is a flight with F passengers departing (ie QF9 and QF93)? Or is it just the 4 hours prior to the departure of QF9 and QF93? ie opening time to 0935 and then 1130-1530 with a gap of 930-1130 where it is closed...? If anyone knows that would be great. I should've asked at the time.
Anyway, when QF9 departed, it became like a ghost lounge.. I was still there eating on my lonesome with hardly any staff around
I guess for next time if I am on QF133 again with HLO I could get there before 11am and sample both the breakfast and the lunch menu!
As you are flying transtasman with carry on only from Melbourne airport you can use the International Q Card Readers. You can check in and the express lane logo is printed on the BP.
Thanks, totally forgot about trying that. But on the way home AKL-MEL I was at the airport early (about T-6) and couldn't print my BP beforehand so after trying the Int Q card reader it got declined, telling me to go to a service desk. I went to the OLCI bag drop and had a BP printed for me. So, maybe the NGCI poles for Trans-tasman flights are only able to be used to print BPs when the flight is open (ie within T-3)?
IIRC the dom NGCI poles can print BPs even 9 or 10 hours before departure...
