All spectators at 16 pilot trial events will be required to abide by a code of conduct which includes remaining seated where possible and avoiding contact with others outside their social bubbles.
Spectators will also be required to wear face-coverings at all times, download the HSE Covid-19 contract tracing app and follow the advice of staff and stewards.
Pilot events include GAA, camogie and ladies' football, League of Ireland games, rugby matches and other sports such as golf and athletics.
The first events take place on Friday and include Leinster v Dragons at the RDS, Shamrock Rovers vs Finn Harps at Tallaght Stadium and Cork City vs Cabinteely at Turner's Cross.
Stadiums with capacities in excess of 5,000 people will be limited to maximum attendances of between 200 to 500 people initially.
For the trial events no food and beverages will be available and entry times will be staggered to allow for efficient and safe throughput of fans.
Government Chief Whip Jack Chambers on Monday published updated guidelines for re-opening sportsgrounds which were drafted by a working group of sporting event experts and health and safety advisors.
They provide for mitigation measures to allow for the safe return of spectators to sporting events.
These include advance communication with attendees, venues operating at reduced capacities, physical distancing, mask wearing and hand hygiene.
A “robust” contact tracing system will also be in place.
These events will be used to evaluate and review progress towards increasing spectator capacity at events in July and August.
“I am acutely aware how eager fans are to see their home county, local club or sporting heroes in action once again,” Mr Chambers said.
“These expert-led guidelines are significant because they chart a clear path back to allowing large numbers of spectators attends games once again.
“They cover a huge range of areas from ticketing and arrival at the grounds, to public transport and communications with fans, stadium signage, contact tracing and a host of other important factors.
“The guidelines can be continuously reviewed after each pilot event and will ultimately pave the way for much greater numbers to attend sporting events as we progress into summer and autumn.”
The working group will monitor the events and adapt approaches, if needed, as progress is made towards larger attendances later this summer.
There will be contact tracing tied to each ticket which will be held for 28 days, to enable sports groups help the HSE if there is a Covid-19 case linked to the event.
Later in the summer, as more and more people are vaccinated, there may be scope to increase attendances further.
Event organisers will have primary responsibility and will liaise with the local authorities, public transport providers, the Garda and others.
The organisations have worked with their ticketing partners to ensure a robust track and trace will be in place and this system has already been trialled in the UK.
