Thorpe, 31, was taken to hospital for the second time in as many weeks after being spotted in a suburban street in southern Sydney at about 3am, according to Ten News.
A 14-year-old boy raised the alarm after hearing a noise outside his family home and seeing Thorpe attempting to gain entry to a van in the driveway, Ten said.
He was reportedly "dazed" and under the influence of something, the network reported.
"He was taken to hospital for medical assessment," a spokeswoman said.
"No official complaint has been made and no further police action is anticipated."
Thorpe's management did not immediately respond to requests for comment but Ten later said they had confirmed that he had been admitted to a private rehab clinic for depression treatment.
Ten said his management told them Thorpe's "disorientated" state was due to a mixture of painkillers and anti-depressants.
