Regular public transport users who want to buy monthly, quarterly or yearly tickets face their last chance on Sunday as the state government forces more commuters on to its electronic Opal card system.

Weekly, monthly and yearly train passes for adults are among 14 paper-based tickets being "retired" from Monday, while bus and pensioner tickets remain.
