In total, the woman was convicted of six charges of obtaining by deception, with the total amount of money she received fraudulently reaching $26,606. She spent it all.
Judge Ryan told the court the deception began in 2014, when the woman told friends and family she had been diagnosed with terminal cancer.
Fundraising was set up on Givealittle and through the Angel Project, and cash and goods were donated by a school board of trustees, Harvey Norman and Honda.
When her deception became apparent, the woman told police she was someone who "had a lot of illnesses and ... didn't mean for it to go this far".
In a pre-sentence report, she indicated her offending was not deliberate, but Judge Ryan said she did not accept that.
"You knew what was happening and you enjoyed what was happening ... you enjoyed the attention. You took the money and you spent it."
However, she accepted a clinical psychologist's finding that the woman suffered from factitious disorder.
She had a history of somatic complaints and had been admitted to hospital 50 times between 2009 and 2014.
Judge Ryan said there was a direct link between the woman's condition and her fraud.
"While that might reduce your culpability to an extent, it doesn't take it away entirely. I must impose a sentence that is punitive, but primarily therapeutic."
In victim impact statements, Givealittle and the Angel Project leaders expressed fears the woman's actions could affect people's confidence that causes they were giving to were legitimate.
Those speaking on behalf of Honda and Harvey Norman said the companies would not support similar requests in the future, and the woman who spent $7000 for a concert that never took place said her family were "heartbroken" by the woman's deception.
"This was to be a wedding gift ... our daughter would've absolutely loved it, but we have never told her what happened as we know it would hurt her."
