Within six months the state government will be making $1 million a week out of expensive train fares to Sydney Airport, but it continues to insist fares should not be lowered.

A parliamentary committee is scheduled to report in coming days on proposals to lower the cost of catching a train to Sydney Airport. An ''access fee'' charged by the private operators of the stations adds $12.60 to the cost of an adult train ticket to the airport.

But because of a revenue sharing agreement with the station operators, the state government will be pocketing $4 million a month from these access fees by August, according to information provided to the committee by Airport Link Company.

The tourism industry, transport advocates and community groups agree that the fees should be cut to make it more attractive to catch the train to the airport, surrounded by notoriously congested roads.
