A jury is considering its verdict in the trial of a man accused of a "harrowing" attack on two female backpackers at a remote South Australian beach.
The 60-year-old man is accused of sexually assaulting a Brazilian woman and hitting a German woman over the head with a hammer at Salt Creek, east of Adelaide, in February 2016.
SA Supreme Court judge Trish Kelly summed up the case on Friday morning before the jury of 11 was sent out at about 11.30am to consider their verdict.
Prosecutor Jim Pearce QC delivered his closing submissions on Thursday, saying the two backpackers were honest and reliable young women.
"There is no mystery here about what happened. There is no mystery because the two women told you," Mr Pearce said.
"You saw two very impressive young women who sat in the witness box and did their best to describe to you a very harrowing ordeal."
But defence lawyer Bill Boucaut QC said there were a number of "oddities" in the case, creating doubt about what really happened that day on the rugged sand dunes.
These odd features include the fact that the hammer, knife and rope allegedly used in the attacks were never found.
"Where are these things? It is more than a bit of a mystery," Mr Boucaut said.
The accused man met the backpackers online and drove them to a remote spot among the sand dunes before setting up camp.
It is there that he allegedly dragged the Brazilian woman to the sand, tied her up with ropes, cut off her bikini with a knife and sexually assaulted her.
He then allegedly came after the German woman, hitting her in the head with a hammer four times and repeatedly ramming her with his 4WD as she fled.
Both women escaped and the man was arrested in his car.
The man has pleaded not guilty to attempted murder, kidnapping with intent to rape, indecent assault and several other offences.
