Australian Rugby League Commission chairman Peter V'landys aims to get crowds back to NRL games as early as July 1.
After a two-month absence, the revamped NRL season resumes on Thursday, when Brisbane Broncos host Parramatta Eels.
Due to the ongoing coronavirus pandemic, no spectators are allowed at venues and clubs must limit the number of people they take to the stadium.
"We're on the moon," V'landys told the Sydney Morning Herald. "We're looking for Mars now.
"The next test for us is, once they relax the measures, we want to see in the next three weeks if the infection rate is altered in any fashion. If it hasn't, we'll be pushing very hard for crowds... capped crowds."
The NRL will be Australia's first major sporting competition to resume, joining only very few countries in having professional sport back running.
In Taiwan, spectators are allowed to attend baseball games, but must undergo temperature checks, wear face masks and sit at least one metre apart.
Fans attended round one matches when the NRL kicked off, but games were played behind closed doors the following week and that will continue until fans are allowed back.
"In ANZ [Stadium], you might be able to get 20,000 with social distancing, whereas somewhere like Kogarah, you might get 5000," V'Landys adds.
"I am only guessing these figures, but it is absolutely on the radar. That is the next challenge."
The New South Wales Government has permitted up to 50 people in pubs from June 1, and that date looms as a key factor for V'landys and whether the NRL can re-introduce crowds this season.
"We based our return on analysis and information on infection rates, and how the coronavirus really caused the damage it did," he says.
"When you look at it, 60 percent came from offshore and even today, the four positives all came from overseas.
"You take the Ruby Princess out and that's less risk again, so in real terms, if the infection rate stays as low as it does and nothing new is coming in from overseas, the risk is going to be pretty low.
"So why wouldn't we have crowds? We'll do that in the same fashion we did with the return of the game.
"The next test for us is once they relax the measures, we want to see, in the next three weeks, if the infection rate is altered in any fashion. If it hasn't, we'll be pushing very hard for crowds... capped crowds."
