Third airport flagged for Melbourne

Domestic air travellers could take a plane from a third airport on Melbourne's south-eastern fringe under a new strategy to be released today.

Planning Minister Matthew Guy is expected to release a discussion paper today that flags a third airport, claiming road traffic is choking Melbourne Airport at Tullamarine.

Tooradin, south of Cranbourne, is listed as an option for the new airport in the Metropolitan Planning Strategy discussion paper, the Herald Sun has reported.

Business groups have previously suggested Tyabb and South Gippsland as locations for a third airport.

The airport could initially take 300-seat domestic planes with room to expand to international planes and flights, it was reported.

The discussion paper is believed to suggest that Melbourne and Avalon airports are inaccessible to Melbourne's south-eastern fringe, an area with a population the size of Adelaide.

Melbourne's population is expected to reach 6.4 million by 2050.

Mr Guy suggested in a newspaper today that a new airport could be developed through the private sector.
