From next month, a commuter catching the train from Wollongong to Central for work will pay an extra 18 cents every trip.
That's because the government has announced a 2.2 per cent Opal fare increase, which will come into force on July 2.
Transport Minister Andrew Constance said was in line with inflation.
It is also lower than the annual 4.2 per cent increase recommended by the Independent Pricing and Regulatory Tribunal in 2016.
“Since the introduction of OPAL in 2012, this government has kept the fares low with a five-year fare freeze and then the introduction of an adjustment to fares by CPI only last year, and again this coming financial year,” Mr Constance said.

Gold Opal Cards will remain at $2.50 travel for all day travel any day of the week.
The Transfer Discount of $2 every time a commuter changes modes of transport during a journey also remains unchanged.
However, the weekday, weekly and Sunday travel caps will all see a slight increase.
