Most ACT government, irrigated turf sportsgrounds will close from Monday for two-weeks to prepare them for the winter sport season.

However, 21 ovals will remain open to allow teams to continue training.

As well as winter sports such as football, rugby league and Australian Rules, bookings have been received for Canberra Quadball (formerly ANU Quidditch); two Ultimate Frisbee groups, who are training for the National Championships as well as Capital Football, who are preparing for the Football Australia knockout cup to use the ovals that will remain open.

Larger ovals such as the Gungahlin Enclosed Oval, Greenway and Woden Park will be open to allow use by some sporting groups.

The traditional sportsground maintenance period is carried out twice yearly, at the beginning and end of the summer sport season, and involves top dressing fields by spreading a new layer of sand and soil, upgrades to turf, installing goal posts and line marking.

Sportsgrounds that are closed for maintenance will re-open on April 1.

The government says the 21 fields (listed below) that remain open will have maintenance undertaken at a later date when impact to sport is minimal.

• Banks (one field)
• Holt (two fields)
• Bonner (two fields)
• Narrabundah (two fields)
• Duffy (one field)
• O’Connor (two fields)
• Gungahlin Enclosed Oval (one field)
• Scullin (three fields)
• Greenway Oval (one field)
• Yarralumla (one field)
• Griffith (two fields)
• Woden Park (one field)
• Hackett (two fields)
