Aaron Finch's side is being told by CA not to shake hands with their opponents and will also be briefed about shining the ball with saliva and other bodily fluids.
CA's coronavirus task group spoke to Finch's team on Thursday night and were told of players'concerns about playing in front of a crowd.
"The feeling from the men's team was there was some apprehension based on the experience of Sunday night,partly,and the uncertainty of the situation and the developments around the world,"Roberts said on Friday.
"The safety of our players is paramount. We've offered all our people the opportunity to work from places where they feel most safe,like most employers have around Australia and no doubt other parts of the world.
"And it was only right we afforded the same flexibility to our players and worked through that with them.
"They're comfortable to play the matches. They're looking forward to taking on NZ this afternoon and they're feeling safe by virtue of playing in unusual situation of empty stadia but the situation that enables them to go about their business on the field and inspire Australians with the bat and ball this afternoon."
Australia's players appear likely to follow the practice of not shaking hands. The England,India and South Africa men's teams have said they will not be shaking hands,while the Pakistan Cricket Board has advised players and staff involved in their Twenty20 league to do likewise.
"We're briefing players on changing some of the standard on-field behaviours such as not shaking hands,"Roberts said.
"Obviously sharing the same sentiments that you feel when you do shake hands with someone to make sure players keep a bit of distance from each other."
Roberts said it was the"right thing to do"to play the women's T20 World Cup final,as the situation has changed markedly since Sunday night.
Unlike Australia's major football codes,the home cricket season is almost over,limiting the economic impact of the crisis on the sport.
The CA board made the announcements on Friday after being told of recommendations by the coronavirus working group the night before.
"We've taken what we believe is a well-balanced decision. We obviously experienced last Sunday night that a member of the crowd at the women's T20 World Cup,was later diagnosed with coronavirus,and it's important that we learn from that,"Roberts said.
"What we've learned from that,the decision we've made,is to go ahead with these ODIs today and on Sunday and next week,but they'll be played without crowds in attendance. We think it would've been excessive to cancel the matches.
"Had we gone ahead as planned,we think that would've been a failure to learn from what we experienced last Sunday. So we're confident that in a situation that's not ideal,we've made a well-balanced decision."

Japanese side the Sunwolves are already marooned in Australia after their home fixtures against Australian and New Zealand teams were moved to the southern hemisphere.
"Super Rugby is an international cross-border competition and with the global outbreak of the coronavirus in recent weeks we always knew that unfortunately at some stage there would be an effect on the tournament,” SANZAAR boss Andy Marinos said.
