ENDEAVOUR Park, Kings Langley and Grantham Heritage Park, Seven Hills, will be the first Blacktown mega parks.
A recent council report has identified funding options for two of five mega parks.
It includes $800,000 each from the new major park reserve and infrastructure sinking fund and reallocation of $1.6 million currently allocated to Grantham Heritage Park.
Each mega park, to cost $1.6 million, will include picnic and playground facilities such as climbing nets, swings, flying foxes and slides.
Funding sources have yet to be identified for the Ward 1 park at Patersons Reserve, Quakers Hill and Plumpton Park in Ward 5.
Dawson Mall was supposed to become first mega parks. The Ward 4 mega park will be the last built — at a site yet to be decided.
Councillors deferred the Ward 4 mega park location earlier this year after concerns about a water-based play area near Westfield and the Mount Druitt Hub.
The three councillors in Ward 4 have asked for a design assessment of whether Dawson Mall is big enough for a mega park.
Bill Colbourne Reserve in Doonside, Woodcroft, The Waterholes at Mount Druitt and Kimberley Reserve, Rooty Hill, have been mentioned as alternative Ward 4 locations.
"It's been difficult to work out an ideal location but we're leaning towards Dawson Mall," Councillor Stephen Bali said.
"Regardless of where we put it, other areas will miss out. We have one bite of the cherry so we need to make the right decision."
The matter is expected to be debated at next week's council meeting.
