Courses in leading teams, digital security basics and creating a brand presentation are among those on offer, Minister for Skills and Tertiary Education Geoff Lee announced on Thursday morning.

He said the 13 new courses have come following an overwhelming response to the initial suite of courses announced earlier this month.

"85,000 people have taken up that option of fee-free courses," he said of the initial course roll-out.

"It's been so successful that some of those [initial] courses are actually full, ones like medical administration have some 10,000 enrolments."

Mr Lee said the 13 new courses are in critical skill shortage areas and they are being offered free online to NSW residents.

"It is a fantastic ability for those who are on JobSeeker, those that are on JobKeeper or those who are quarantined at home where they have spare time," he said.

"It's a wonderful opportunity for people to upskill, re-skill and even change the jobs we're doing."

Mr Lee said these course will be part of the COVID-19 recovery in NSW.

NSW Premier Gladys Berejiklian these new courses would replace those which have reached enrolment capacity to ensure there are still 21 accredited courses available for people to study through TAFE NSW.

"The incredible uptake to the initial 21 fee-free short courses shows that while many businesses across NSW are in hibernation there is a strong desire to upskill and gain new qualifications during this challenging time," she said.

"Some courses have reached their capacity for now so they have been replaced with new courses so that we can continue to provide opportunities for people to upskill during this time."

The 13 new short courses include:

Mr Lee said more than 33,000 people who enrolled in the fee-free courses were studying at TAFE NSW for the very first time.

"The NSW Government is committed to providing opportunities for people to upskill so that they can get the promotion or job they want once this pandemic ends. I encourage everyone to use this time to increase their skills," he said.
