Total fuel costs for the six months to December 2007 were $28 million lower than the same period last year. The underlying into-plane fuel price was 11.9 per cent higher than the prior year, increasing costs by $175 million, while increased flying added $68 million in costs. Hedging benefits were $147 million higher than the prior half-year before an adverse effect of hedge accounting ineffectiveness which increased costs by $57 million. Favourable foreign exchange rate movements reduced fuel costs by $203 million. Fuel costs would have been $26 million higher had it not been for SFP initiatives delivered during the half-year.
