Sport Australia launched its return to play toolkit last week, giving national sporting organisations and community sports clubs guidelines for post-coronavirus training and competition.

The ACT government lifted some restrictions on Saturday, allowing indoor sports in groups of 20 and outdoor training to progress to groups of 20 as well.

Most competitions are hoping to start in mid-July, giving them a three-month window to compete before summer sports resume.

Dalton reassured parents and grandparents they would not have to watch from the car or be banned from attending weekend fixtures, but did ask for families to help the 3.1 million volunteers in sport to ensure the resumption goes smoothly.

"Our intention is not to burden millions of sporting volunteers with rules and red tape," Dalton wrote in an open letter.

"... Put yourself in this scenario, the local junior netball or footy competition has been given consent by the local state government to resume. Children, families and communities flock to congested local venue en masse to cheer on the kids and celebrate.

MORE CANBERRA SPORT

"Now think about the role of sporting officials, the bulk of them volunteers, who are trying to manage everything from competition schedules, venue preparation, match officials, operational procedures. Then add the complexity of the pandemic.

"...There are two key priorities. The first is supporting of sporting administrators, many of them volunteers. The second is winning back our participants."

ACT Sport and Recreation has been hosting regular online seminars to give up to date information about restrictions and planned changes to allow sport to start.

Canberra rugby clubs will officially train for the first time this week after being set a June 1 resumption date by ACT rugby and Rugby Australia.

Canberra rugby league is waiting for the NSWRL plan to be approved by the NSW government before their teams can train and play.

"We will all have to play a role in a safe and sensible return to sport. We may only get one shot at it this year, so we need to do it right," Dalton said.

"We cannot decide when sport returns, those are the decisions for State and Territory Governments and are based on the very best health advice. Public safety is paramount.

"But when sport is back, we will need you all back too. Join a team, sign-up for a membership, volunteer to help. Let's ensure sport doesn't just survive, but it thrives again."

Basketball ACT and Netball ACT have been granted exemptions to exceed the 20-person indoor limit because walls separate their multi-court venues.

Canberra teams are concerned about restarting sport without proper health measures in place given the age bracket of their volunteers, fearing they would be putting them at risk if they reopened gates.

AFL Canberra teams are keen to play for points despite the shortened season, while Capital Football is doing models for an 11-week competition.
