A man accused of drugging and raping three teenage girls in Brisbane last year is "lucky" to be released from behind bars, a court has been told.
The 21-year-old, who cannot be named for legal reasons, was granted bail when he appeared in a Brisbane court on Tuesday.
The apprentice mechanic, two men aged 24 and 20, and a 16-year-old boy were arrested on Thursday over the alleged offences committed on December 19.
It will be alleged the four invited three girls to a party in a Toowong unit, where they were drugged and sexually assaulted multiple times, police said last week.
Two of the girls consumed alcohol and cannabis, while the third had only alcohol, the court heard.
While it is not claimed they consumed the substances unwillingly, it will be alleged the alcohol and cannabis were given to the teenagers to stupefy them.
Few details of the alleged offences were heard in court on Tuesday, but it is alleged one girl was repeatedly raped after passing out and another was described as being "woozy".
The crux of the evidence against the 21-year-old is that his DNA was allegedly found on the inside of a condom, while the DNA of one girl was on the outside, magistrate Noel Nunan said.
"You make sure you don't get into any more trouble," Mr Nunan told the 21-year-old after agreeing to his release on bail.
"You're a lucky man, I suspect, to be getting out today."
The man, who was already on bail on other unrelated charges, is charged with raping one girl five times and the others once each.
He is also charged with two counts of indecently assaulting one teenager and administering a stupefying drug to all three girls.
The man was also ordered to provide a blood and urine sample for a disease test.
Police have appealed for anyone with further information or victims of similar incidents to come forward.
The 21-year-old is expected to appear in the same court with the two adult co-accused on April 27.
