Transport Minister Gladys Berejiklian announced on Thursday the government was recruiting 65 more Transport Officers who would join the 150 officers already working alongside the Police Transport Command on NSW public transport.

The government said the extra officers would be used to target Wollongong and other regional areas such as the Blue Mountains and Central Coast. Their main brief was to target fare evaders.

"Fare evasion costs taxpayers millions of dollars a year, and while the majority of customers do the right thing, it's frustrating when others don't pay their way," Mrs Berejiklian said.

She also said Transport Officers now had a high-tech response to fare evasion.

"Transport Officers are now equipped with a hand-held smart device, which automatically sends infringement notices in the post," she said.

Transport Officers also used hand-held Opal readers to scan customers' Opal cards to ensure they had tapped on correctly.
