"Greeley" is a well-known Australian hip-hop artist who did a year in Risdon on trumped up charges where he spent his entire time writing his last album "Risdon Wisdom"
Whilst inside he did workshops with other inmates helping them channel their creativity for more positive things. He's done lots of community work and is a well respected figure in the Australian hip-hop community. This cache is to acknowledge the hard work he does.
Didnt want to be seen burying anything too close to the prison grounds in case they thought we were up to something fishy.
The face on the cache is Greeley. Look him up, worth listening the lyrics on his album. Lots of powerful messages.
