Melina Roberge, 24, broke down in tears Wednesday when the Sydney court handed down the sentence, which includes a non-parole period of 4 years and 9 months in prison.
Roberge's Instagram account disappeared after her arrest.
Judge Traill said Roberge had been "seduced by lifestyle and the opportunity to post glamorous Instagram photos", along with the potential financial windfall she stood to make as a result of the trafficking ploy.
Roberge admitted that she arranged to be a drug mule with a "sugar daddy" in exchange for a free vacation to Australia and the cruise ship passage.
Roberge, Lagacé and André Tamine, a 65-year-old Montreal man, were all arrested upon arriving in Australia on August 28, 2016.
One of her accomplices, Isabelle Lagace, 30, was sentenced in November to at least four-and-a-half years in jail after admitting she tried to smuggle the white powder in the pair's cabin to clear a $20,000 debt.
The third accomplice, Andre Tamin, 65, will be sentenced in October, the Star reported. "I doubt she is now", Judge Traill said.
Barcelona Eyeing £60m Martial Deal
And Barcelona , according to reports in Spain, are lining up a deal for the man whose current contract ends in the summer of 2019. An Old Trafford source is quoted: " Marcus loves it here but there are concerns with what the boss could do this summer ".
The judge also said the crime was a "very sad indictment" of the social media generation who "seek to attain such a vacuous existence where how many "likes" they receive are their currency".
Roberge and her travel companion, Isabelle Lagace, posted glamorous pictures of their travels while on the cruise ship on social media. "Sometimes there would be intimacy but not always". It was there she was approached to join the drug trade.
Roberge said she apologized to people who were struggling with addiction. She said he invited her to go on a drug-smuggling trip to Morocco the next year.
Traill said the then 22-year-old was "there to look pretty", acting as a decoy to the drug dealing below deck.
Everything pertained to an end in July 2016, when she accepted a complimentary journey on the Sea Princess, a high-end cruise liner that made drop in numerous nations in the southern hemisphere, consisting of Colombia, Peru, New Zealand and Australia, reports CBS.
The judge also said Roberge had a sexual relationship with her so-called "sugar daddy", who is a "much older man", the Post reported.
She realized, she told the court, that she had put everything on the line for some selfies "in exotic locations and post them on Instagram to receive "likes" and attention".
