PINT and St Mary's will meet in a Women's Premier League grand final for the first time after a classy Saints side beat Nightcliff in the preliminary final.
The Ryan Smith coached Saints wasted several scoring shots in the first quarter before finding their range in the second and running to a 47-point win.
The 7.13 (55) to 1.2 (8) win sets up another shot at reigning premier PINT in Saturday's Big Dance, the first time three-time WPL premier St Mary's have played in a premiership decider since 2012/13.
The club's premiership drought has stretched to 14 years since beating Waratah in the 2009/10 grand final, something coach Ryan Smith said the club was working towards finding a solution.
"The club's excited about what's ahead of us, our women's program is outstanding where the Div 1 girls play in a grand final against PINT on Wednesday night and the 14s and 16s won this week,'' he said.
"Plus the 18s made an elimination final and the under-12s are in a grand final, so the women's pathway program has certainly been outstanding this year and we're happy to be there and leading by example as a Premier League side.''
Smith said his players' emphasis on playing team footy and being first to the ball had paid big dividends in their fourth win over Nightcliff this season, including two finals matches.
"Last week (second semi-final against PINT) we were caught behind too much with PINT having a number of important possessions more than us and it was something we identified at training,'' he added.
"We had a really big week preparing for what was an elimination final, something that was much harder than normal, but it was what was needed and the girls responded by putting a winning score on the board.
"We had players like Latoya (Tipiloura) and Lavinah (Pollo) among a lot more role players who chipped in to help take the load off the Danielle Ponter, Jo Miller, Billie Byers and others.''
Smith described Miller's game out of the middle as outstanding on her return to the side from SANFL duties, along with those of Ponter, Janet Baird and Byers.
"The difference this time was there were other players contributing to enable us to keep the ball moving forward in preparation for next Saturday's grand final, which will be a terrific game for women's footy,'' he said.
Nightcliff lost no friends with the loss in what was Andrew Rock's first season in charge as senior coach.
Cassie McWilliam was superb in the ruck and up forward where she kicked a clever goal in the third term, Hannah Turnbull never stopped trying in the last line of defence and midfielder Maighan Fogas showed why she is so highly rated at Tigerland.
The Lady Tigers won 11 of 16 games in the home and away season, four of those losses coming at the hands of both grand finalists.
Their 40.16 (256) score against Wanderers in Round 3 set a new WPL record, a scoreline that almost fell to St Mary's a week later when they finished four points short.
