Upgrades to the war memorial and new community parkland were completed earlier this year, with future upgrades priced at more than $1.5 million.
The overall cost of the Charles Riley redevelopment will total more than $10 million once completed.
Stirling Mayor Giovanni Italiano said the new ovals would have the capacity to accommodate two junior football matches, instead of one, as well as six athletic throwing circles.
The redeveloped space would also provide enough space to host senior football games.
Cr Italiano said the project had been seven years in the making and the City had consulted regular users and the community widely on this project.
�At a stage one cost of just over $1.2 million, of which funding of $370,000 has been provided by the Department of Sport and Recreation via their Community Sporting and Recreation Facilities fund, the community is set to be the big winner when this stage is complete,� he said.
Cr Italiano said the senior oval could still be used by the North Beach Amateur Senior and Junior Football Clubs, with some teams relocated to Lake Gwelup, Karrinyup and Aintree Reserves.
The dog exercise area would include an enclosed space, while Cr Italiano said more than 140 trees would be planted.
