A judge called the scam "despicable".
Melbourne Magistrates Court heard that Hanna Dickenson was partying hard and needed money to live a party lifestyle, involving drugs, alcohol, and worldwide holidays.
Her parents had received donations from their friends, a court was told.
7 News reports that Dickenson arrived at court with her mother, who is one of the people she scammed - and pleaded guilty to seven charges of obtaining property by deception.
When someone you know is diagnosed with cancer, you'd do - and give -anything to help that person overcome a disease that seems to be more lethal than not.
Magistrate David Starvaggi said "Ms Dickenson engaged in conduct that tears at the very heart strings of human nature".

Gold Coast organising committee chairman Peter Beattie said he wasn't surprised and it was something that happened at other games. Of the missing, six had competed without winning medals, while two were still to take part in the Games.
"People's conscious desire to assist has been touched. that's the social trust".
Dickenson's scam was uncovered when one of her victims discovered photos on her Facebook profile, which made him suspicious about claims of her illness.
She also compared the deception to one involving an Australian celebrity blogger, Belle Gibson, who was fined A$410,000 past year after falsely claiming to have beaten brain cancer.
Gibson chronicled her battle with cancer on a blog, The Whole Pantry, which spawned an app and recipe book.
However Mr Starvaggi said the cases were not directly comparable, and that the court needed to deter others from engaging in similar conduct.
Lindsay said she'll likely appeal her client's sentence. The views expressed therein are not necessarily those of stlucianewsonline.com, its sponsors or advertisers.
