Limewood, I strongly recommend you call QF, cancel the points usage for Starclass and incur a small points cancellation penalty. QF are charging you Business points for a Premium economy product (Starclass). You are far better of keeping those points for use in real business class (say A380 flat bed).
You may even consider paying for an On Departure Upgrade fee at HNL ($300?) to move from economy into StarClass if available at the time.
I concur with goldmember - save the points and buy an extra legroom seat in economy instead (not very expensive). Otherwise the points are only buying you the premium check-in and lounge access (oh, and meals i suppose- but only in terms of $$, the quality is the same as economy).
While the seats may be similar, I don't think the service is anywhere the same as Qantas domestic business class.
While the crew make a good show if the limited resources, and they have little touches like a paper tray cover (to simulate the cloth ones in business), and the have plunger coffe, there is not much else lie domestic business.
beverages are served in plastic 'glasses', the food is in foil and with plastic cutlery.
Breakfast is a hot gooey cheese english muffin, or similar - on my last flight the pursar had to write it up in the log becuase it was so bad (most passengers returned it).
The best seats for two passengers I think are 1EF. There is legroom and no-one reclining on you.
The next ones I would go for ar 1AB.
1JK should be avooided as the area immediately in front is part of the galley where they have extra crew seats and when they sit and chat it can be very noticeable.
