Teams of cleaners and marshalls have been rolled out at Illawarra transport hubs to deal with the increase in commuters.
From Wednesday separate teams of "Sanitation and Hygiene Agile Response Cleaners" will be operating at Wollongong station and the interchange at Marine Drive.
They will be boarding buses at both locations to scrub down high contact areas such as stop buttons and Opal card readers.
"These SHARC teams work seven days a week and clean the buses during layover stops therefore they don't cause delays to the timetable," a Transport for NSW spokeswoman said.
This is on top of extra cleaning regimes that have already been introduced by the region's bus companies.
Transport for NSW is also rolling out mashalling officers at hotspots across the rail network, including Wollongong and Shellharbour, to ensure the COVID-19 guidelines are being followed.
"Marshals will monitor physical distancing, assist with crowd management and provide extra guidance to customers to help them move through stations and interchanges safely," the spokeswoman said
"Marshals will assist with controlling access to platforms, stations and interchanges to manage numbers appropriately, they are not there to enforce physical distancing through fines or penalties."
