The 32-year-old faces one count of sexual intercourse without consent after the Crown withdrew three additional charges last month.
Gunathilaka has entered a not guilty plea to the remaining charge and will stand trial, the Downing Centre Local Court was told on Thursday.
His lawyer Alen Sahinovic said the charge relates to stealthing, which is the practice of removing a condom during sexual intercourse when the other person has only consented to condom-protected sex.
Police allege the batter met up with the 29-year-old woman at Sydney's Opera Bar after matching with her on Tinder in November 2022.
The pair then returned to her home in Sydney's eastern suburbs before Gunathilaka allegedly had "forceful" sexual intercourse with her, choking her repeatedly.
After 10-15 minutes she noticed the condom she had asked him to wear was laying on the floor next to the bed.
"The complainant was in shock and did not say anything out of fear of retribution," a police fact sheet said.
Gunathilaka is attempting to have his bail conditions eased so that he is only required to report to police three times a week, instead of daily.
Mr Sahinovic argued the reduction in charges against him, as well as his lack of criminal history, merit less onerous bail conditions.
Magistrate Susan Horan is waiting for an up-to-date fact sheet before deciding on the application, saying the "risk of failure to appear is still present".
Gunathilaka had his bail varied in February to allow him to use the WhatsApp messaging service and go out at night after he was banned from using Tinder and other social media platforms when originally granted bail in November 2022.
