Mundell underwent emergency surgery and the drugs were removed from his body and seized by police.
The Crown handed out two charges to Mundell: Importing a Class A controlled drug and possessing the drug for supply.
However, Mundell argued in court all of the methamphetamine was for his own use and in court, the judge found he was addicted to the drug.
The judge also found Mundell had not established whether there was not a commercial aspect to the importation of the drug.
After being handed down the 30-month term, Mundell appealed to the High Court and argued the judge had not acted in accordance with the Sentencing Act.
The appeal was allowed and Mundell's sentence was thrown away, the case has been remitted back to the district court for re-assessment and re-sentencing.
