There are orienteering events available right throughout the year.  The orienteering season is loosely grouped into 2 seasons - Winter and Summer.

Winter

The main orienteering season is the winter season which runs from March through to October.  There are orienteering events on most weekends during this period.  The season generally starts around the time of the Australian 3 Days carnival which is held at Easter and concludes with the Australian Championships which is held in the last week of September and first week in October. 

There are a variety of styles of events.  There are great bush orienteering events just outside Sydney as well as plenty of events in parkland and urban bush areas within the meotrpolitan area. 

The main events during the winter season are:

• "Come and Try It" events (CATI)
• MetrOLeague
• Sydney O Series
• State League
• Australian 3 Days
• Australian Championships

There are also mountain bike orienteering (MTBO) events held during the winter season.  The main MTBO events during the winter season are:

• MTBO Super Series
• MTBO Australian Championships
  
• 6 Hour Enduro

Summer

The summer season starts in October and runs through to March.  These are mostly sprint style events held in parks and urban streetscapes in the metroplitan area.  The main events are the Sydney Summer Series which is held each Wednesday during the summer season and the Sydney Parks Series which is held on Monday evenings during January and February.  These events are followed on by the Autumn Evening Series which overlaps with the Winter season. 

There is also a 5 day orienteering event held in rural bushland just after Christmas.

• Sydney Summer Series
• Sydney Sprints
• Christmas 5 Days
• Autumn Evening Series

The schedule of events for the summer and winter seasons can be found at the 2010 Event Calendar.
