Construction is now under way at the new Tahmoor District Sporting Complex.
The new complex is expected to transform the existing facility into a district level sports precinct that will meet the long-term needs of Wollondilly.
New netball courts and an athletics field will be completed as part of the project.
Wollondilly mayor Matthew Deeth said the project would give local teams an exciting new space to play.
"Planning with the community through the master plan process has allowed us to turn the existing Tahmoor Sportsground into a modern, user-friendly facility that our local sporting groups and the community can be proud of," Cr Deeth said.
"The upgrade will ensure longevity of the site as a district level sporting complex to cater for Wollondilly's growing population over the next 20 years."
Wollondilly MP Nathaniel Smith MP echoed Cr Deeth's sentiments.
He said he was "looking forward to turning up to the Tahmoor District Sporting Complex in years to come to watch sporting events for all ages and cheering on our local teams at a fantastic new sports facility".
The council will use funding from the $190 million Western Parkland City Liveability Program to bring the first stage of the master plan to life.
The program is part of the Western Sydney City Deal, which all three Macarthur councils are a part of.
The federal minister for population, cities and urban infrastructure Alan Tudge said community infrastructure was key to the Morrison Government's jobs-led recovery from Covid-19.
"The Western Sydney City Deal is creating jobs and boosting quality of life," Mr Tudge said.
"Kicking off construction on the Tahmoor District Sporting Complex means local jobs on the ground right now."
NSW minister for western Sydney Stuart Ayres said it was exciting to see projects supported by the liveability program begin to take shape.
"I look forward to seeing this sporting complex become a reality for the people of Tahmoor and the whole district," he said.
Hume MP and minister for energy Angus Taylor said the construction of new facilities was critical to activate new job opportunities for Hume.
"We are creating jobs in local communities to build the foundations of the post-COVID-19 recovery," Mr Taylor said.
Access to the site will be restricted from now until the end of the project.
The area between the soccer fields and the skate park have been fenced as a construction site and will remain so until the construction of the new netball courts is completed in late February.
Water and power supply to the site will be impacted from time to time, with all users notified as required.
Demolition of the old athletics field has started and earthworks will begin at the end of July 2020.
The new athletics field will be available by February 2021, subject to wet weather delays.
The area between the soccer fields and the new athletics field will remain as a construction area for the new facility through until its completion in mid-2021.
The existing netball courts will be excavated to provide fill for new netball courts in conjunction with athletics field earthworks.
Updates on the project and notification of access restrictions due to construction activity will be available on the council's website.
