Paper multitrip public transport tickets will become invalid on buses, trains and trams from December 31.

This morning Transport Minister Stephen Mullighan said the successful introduction of the Metrocard had made the old multitrip tickets redundant.

“Less than half of one per cent of the travelling public still use a multitrip ticket instead of the new metrocard and they are now to be retired from service,” Mullighan said.

The use of the smartcard has grown to 86 per cent of all validations on public transport since its introduction. Adelaide Metro stopped selling multitrip tickets in June last year.

Mullighan said mulitrip ticketholders could transfer remaining trips or money to their metrocard, or exchange the remaining trips for single trip tickets.

Customers can make the exchange until February 28 next year.
