Welcome to the forum
You do not give you location, but assume USA (after all this is world wide web). Do you have experience with first & business class aircraft as flown by non USA airlines and/or long haul international routes? I have met people who expect first in EK, QF, BA, SQ etc to be like a USA domestic first class.
Not many airlines USA to Aust/NZ:- Qantas, UA, Delta, Virgin Australia, Hawaiian & Air NZ
And others via Asia or the south pacific
US is merging with AA some time in the future, so will have only AA miles (QF partner)
Start by looking at each freq flyer programe to see how many miles, and cash if applicable, each would charge.
