Hunt off the hook...or is he?
Hunt, a former Rugby League international who made his Wallabies debut last year, stood down voluntarily from all contractual obligations in December after he was detained in Brisbane during a "random street stop" with another man.
Hunt was originally accused of possessing cocaine but the charge was dropped due to lack of evidence, prosecutors said.
However, he is not off the hook with Rugby Australia.
The governing body said they have "its investigation in relation to his conduct".
Rugby Australia's statement on the matter included: "Hunt pleaded guilty to possession of a dangerous drug (Alprazolam) and contravening a police direction. A separate charge of cocaine possession was dropped.
"The Queensland Reds and Wallabies back will continue his voluntary stand-down from all Rugby duties until the matter is resolved by Rugby Australia and the Queensland Rugby Union (QRU).
"A further update will be provided at the appropriate time."
He was fined Aus$600 (US$475) but no conviction was recorded, with his lawyer arguing that it would limit his movements overseas, the Australian Broadcasting Corporation reported.
Lawyer Adam Magill said Hunt had the Xanax (Alprazolam) tablet to help him sleep.
Outside the Brisbane Magistrates Court, Magill told reporters Hunt was "happy this matter has been resolved, he can move on with his work and we can move forward".
Hunt could be penalised by Rugby Australia for bringing the game into disrepute.
It is not the first time Hunt had been in trouble with the law.
He was banned for six weeks and fined Aus$30 000 by the Reds in 2015 after pleading guilty to four charges of cocaine possession.
As well as his fine he was stripped of the Reds' vice-captaincy, and he was also ordered to pay Aus$2 500 by magistrates on Queensland's Gold Coast.
