The Semaphore Street Fair began in 1994 as an event at the end of a bike race in Semaphore. Street traders would spill out on to the footpath to greet racegoers and provide fun and entertainment for those who came down to watch the end of the bike race. The Semaphore Mainstreet Association (SMA) was formed to oversee the event, and over the years more and more traders became involved, even after the bike race ceased.

The Semaphore Street Fair was organised by volunteers with the SMA for seven consecutive years from 1994 – 2000 inclusive until it was too much for volunteers to manage.

After a break, the Semaphore Street Fair was re-established in 2005 with the support of the City of Port Adelaide Enfield and a part-time event manager. The event is now held annually due to its ever-increasing popularity. The event has evolved from a small local event to one that attracts thousands of people from all over Adelaide.

The event constantly evolves based on feedback from traders, stallholders, the community and the working party. Keeping the event fresh has resulted in an increase of visitors at the event and to visitors returning to the area after this event which has increased tourism and trade over summer.

Today, the Semaphore Street Fair is the largest one-day event in the Western suburbs with more than 50,000 people heading to Semaphore Road each year on the last Sunday in November.

Once a year, event-goers know they can attend the Semaphore Street Fair for some much-needed fun and entertainment in a relaxing family-friendly environment. There are lots of things to do that are free, loads of stalls with interesting and handmade products ideal for Christmas presents and lots to do and see.
