Perth Airport's potential ownership change one of several in Australia

The sale of Sydney Airport early in 2022 was expected to kickstart M&A activity in the airport sector globally.

It didn't do, but there has been an increase in sales activity in Australia - at least, in recent months - as shareholders at three airports have begun to investigate the benefits of disposing of their small shareholdings in airports across the country.

The reasons are complex and are mainly connected to mergers between pension funds, which control many Australian airports, and their need to rebalance their combined portfolios.

On the face of it, Perth Airport - in the far west of the country, and serving a city that is really only accessible by air from any distance - offers a good opportunity for investment, although (a) future one(s) will probably come from within that fund fraternity.
