At the end of the day, London to Oz / NZ is one of the most competitive routes in the world and fare are very low (relative to distance travelled) if you pay cash.
Agreed, and do come back for advice, there are a lot of ways to save meney on the costs that very knowledgable folks on here can help with.
I would suggest though that if you are very flexible with dates, maybe wait a bit longer and push for enough miles to use your 241 voucher on club seats. I have managed about 50,000 from tesco this past four months, which is just from careful use of codes and buying no extra food.
But remember whichever carrier you do go with, if you do spend cash, put it on your AMEX / Tesco card and get some miles back !
