420 Day in Australia

Across Australia, 420 has become both a cultural celebration and, in many cases, a peaceful call for reform. Cities such as Sydney, Melbourne, Brisbane, Adelaide and Perth have seen informal 420 meet-ups, community gatherings, picnics, and public demonstrations over the years. In places like Melbourne’s Flagstaff Gardens, Sydney’s Hyde Park, and Brisbane’s Roma Street Parklands, groups of cannabis supporters have occasionally gathered on April 20th to connect, share conversations, and advocate for cannabis law reform.

When Is The 420 Sale?

The official 420 celebration takes place on 20th April, but at MSNL we like to give our Australian customers a chance to get in early. If it’s already April and you’re browsing this page, keep your eyes peeled — our 420 deals could drop at any moment.

Where Did 420 Day Get Its Name?

The term “420” originated in California in the early 1970s, when a group of high-school friends agreed to meet at 4:20pm to search for a rumoured abandoned cannabis crop. The number became their private code for anything cannabis-related. Over time, the phrase spread through US counterculture and eventually reached countries like Australia through music, festivals, magazines and global cannabis culture. In 1991, High Times helped popularise the term worldwide, mistakenly suggesting it was a police radio code — a myth that still circulates today. By the mid-1990s, 420 was widely recognised as a global celebration, and 20 April (20/4) became the official date. Today, Australian cannabis enthusiasts join millions around the world in celebrating the occasion.
