"She was seduced by lifestyle and the opportunity to post glamorous Instagram photos from around the world", Judge Kate Traill said.
The 24-year-old Roberge, a Canada local who ended up being understood in Australian media as "Drug Babe", wept as she discovered her fate.
Roberge was caught with the drugs on the Sea Princess cruise ship in August of a year ago.
Police with sniffer dogs found 77 pounds of cocaine in the cabin belonging to Roberge and Isabelle Lagace, who was sentenced to 7-1/2 years in prison in November. Authorities have described the drug seizure as the largest Australia has ever had on a commercial boat or plane.
"It is sad they seek to attain such a vacuous existence, where how many "likes" they receive is their currency".
"She wanted to be the envy of others", Traill said.
The genesis of Roberge's downfall was meeting her sugar daddy in a Montreal restaurant in early 2015. Lagace will also probably be deported after serving a non-parole period of four and a half years.
Court documents released after sentencing submissions showed the then 22-year-old was given gifts and money and "if I was interested" she would sleep with the men.

She added: "This highlights the negative influence of social media on young women".
Roberge was also offered $5,000 in spending money to take part in the crime, and was promised more once she came home. Inning accordance with the New York City Post, she stood to make $100,000 from the plot. The ship stopped in Bermuda, Colombia, Panama, Ecuador, Peru, Chile and Tahiti before arriving in Sydney.
She will serve her sentence at the Mary Wade Correctional Centre, a maximum security women's prison.
Ms Roberge pleaded guilty in February, on the eve of her trial, for importing almost 30 kilograms of the drug, in the largest drug seizure on a cruise ship docking in Australia.
She told a Sydney court last month that she had been "excited" about taking the luxury trip which she could not have afforded to pay for.
Wearing a white jacket over a black top and trousers, her face carefully made up and long brown hair drawn up into a ponytail, Roberge bit her lip and wiped her eyes with a tissue in court. They were given first class cruise tickets worth $20,000.
He invited her on a trip to Morocco in May 2016 where she worked as an escort, and it was on this trip that he first asked her to be involved in the drug-smuggling trip.
Fellow Canadian Andre Tamine, 64, is still awaiting sentencing.
