The adjustment means fares will increase between 6¢ and 12¢ a trip for most adult Go Cards.
"Aligning the change with CPI means we have been able to limit increases because we know families are under cost-of-living pressures,"TransLink general manager Martin Bradshaw said.
"Revenue from public transport fares falls well short of funding required to run public transport,and a CPI-based increase simply assists in keeping pace with the current subsidy levels,which has the state government subsidising about 80 per cent of the cost providing public transport."
New TransLink fares from January 2020
- A single-zone trip will increase by six cents to $3.37
- A two-zone trip will increase by eight cents to $4.11
- A three-zone trip will increase by 12 cents to $6.28
But for longer trips covering up to eight or nine zones,fares will increase by 38¢,from $19.96 for an adult during peak travel times to $20.34.
Half-price concessions will continue,with students on concession cards travelling between one or two zones to see a 3¢ or 4¢ increase for each trip.
Fares increased by between 6¢ and 11¢ a trip in January 2018,but were still lower than previous years after a Fairer Fares package introduced in 2017 cut fares by up to 34 per cent.
