Defending champions Sydney will play Northern District in the McDonald's Women's Premier Cricket final after both progressed to the decider without a ball being bowled in Sunday's semi-finals.
The Sydney v Bankstown and NDs v St George semis were both abandoned due to the heavy rain which arrived overnight and stayed around all day.
Sydney and NDs progressed to the Final as the two higher-ranked teams.
They will meet at Bankstown Oval from 10am next Sunday. The women's Second Grade and Under 18 Brewer Shield Finals also take place next Sunday starting at 10am.
Manly-Warringah host Sydney in the Second Grade decider, while in Sydney's third Grand Final next Sunday their women's Under 18 team meet Parramatta for the prestigious Brewer Shield.
The following Sunday, March 28, has been scheduled as the reserve day for all three Finals in the event of inclement weather preventing play.
"You have to feel for Bankstown. They have been one of the form sides since Christmas and deserved to be in the finals," Sydney First Grade coach Russel Grimson said.
"But I am delighted for our girls that their hard work so far has paid off with a grand final spot.
"We put a lot of preparation into the semi but now all the attention is on preparing for what will be a tough game against NDs."
Rangers coach Tommy Anderson was equally philosophical about the semi-final washout.
He said: "Our groundsman was outstanding and we tried everything to get on but the weather beat us.
"It's not the preferred way to win the game but finishing second counts for something and we will take it.
"We are excited to be in the grand final."
On Saturday, Gordon defeated Manly-Warringah to claim the Women's Third Grade Limited-Overs Cup title.
