Brisbane Airport Corporation will accelerate its commercial developments over the next five years and develop 190 hectares of its extensive land holdings as the operator of the country’s third-largest airport seeks to offset weaker aviation revenue.

The $963 million spend, equal to almost half of its existing $2 billion portfolio, will include a near-doubling of onsite power generation through the addition of 6000 rooftop solar panels to account for 10 per cent of the privately owned airport’s needs.
