DJPil,
Much as I would like to visit the outer fringes of Australia as opposed to the proverbial GAFA centre I regret that Cathay Pacific will not deviate from a direct routing Auckland to Hong Kong on 10 May. We will only have the opportunity of viewing the northeastern corner of your fascinating country I fear and this from around FL330.
Our 10week trip to NZ is proving to be excellent in all respects and Avgas prices here are but approximately 0.60GBP per litre................... less than half the UK price....!!
Cheers,
