Queensland Airports Limited (QAL) has completed a major $532m refinancing of its senior debt facilities.

QAL has secured funding from a group of four banks made up of Commonwealth Bank of Australia, National Australia Bank, Westpac and Royal Bank of Canada. The funding is spread across three and five year terms. The new facility refinances exiting debt totalling $468m and provides capacity for QAL to fund further expansion and upgrade works at its three airports in Gold Coast, Townsville and Mount Isa.
