From south of Warragamba, Picton, and Wingello to the towns of Mittagong, Bowral and Moss Vale, people are being urged to spend as the region re-opens for business.

The decision to re-open follows determinations from NSW Police, NSW Rural Fire Service, Transport for NSW and councils.

Minister for police and emergency services David Elliott said tourism was one of the best ways to promote economic recovery and revive small businesses.

"After the horror bushfire season we've had, it's been heartwarming to see the outpouring of community support and donations," Mr Elliott said.

"But the best thing you can do to support a bushfire-affected town is show up with an empty stomach and a full wallet.

"The Southern Highlands has long been a favourite for traditional day trippers and motoring enthusiasts and I encourage everyone to go inject some cash into the local economy, sample a few pies, and thank the local emergency services."

State emergency operations controller deputy commissioner Gary Worboys said much-needed tourism could help businesses get back on their feet following the fires.

"This area was hit hard by recent bushfires and now that the threat has been abated, we want to see people come together and spend some cash to help kick-start the local economy," deputy commissioner Worboys said.

"Plan a day trip with friends and family and see the sights but remember to drive to the conditions and obey the road rules.

"We are also reminding visitors to observe any road closures and respect the privacy of those who have lost homes by avoiding fire-affected areas."
