The action kicks off with the Plate final between Ballincollig and Cill Dara at 12pm. That game will be followed by the Shield final at 1pm between Tralee and Queen's University and the Cup final between Galwegians and Highfield kicks off at 3pm.
In the first of the cup semi-finals, Galwegians travelled to Anglesea Road to take on Old Belvedere and on a bright and breezy day the west was certainly awake.
'Wegians ran in an early try through Mairead Coyne to take the lead and held it right through the half, finishing 10-3 up at half-time.
Coyne scored again in the second half to add to another try from Lisa McDonagh to take the game beyond 'Belvo's reach at 22-8.
Despite a late surge from the home side and a dashing try from Sharon Lynch, the Galway side won out on a 22-13 scoreline.
The other semi-final proved very dramatic as Highfield and UL Bohemians went to extra-time after an injury-time try levelled things for UL. A late, late score from Geraldine Rea in extra-time saw the cup holders through to defend their title.
In the shield semi-finals, the Fermoy Lionesses put up a gallant effort however Tralee showed their Division 1 experience and ran out convincing 20-8 winners.
In the other semi-final it was a much closer affair between Sligo and Queen's University. With 15 minutes remaining Sligo were 19-13 ahead, however they could not absorb the continuous attacking from the Belfast girls as Queen's scored an additional 14 points in those 15 minutes to win the game 27-19.
Perhaps the talk of the night was from the plate semi-final match between Ballincollig and the Rathdrum Drumettes.
It was scoreless in normal time so extra-time had to be played. However, neither team could score here and so a penalty shoot-out was required. Still, after five kicks each, the teams still could not be separated.
It then went to sudden death with each team putting forward their next kicker. On Ballincollig's 12th kick, prop Claire O'Connor stepped up and fired her kick over the bar to win the game and send the Cork girls off to the finals next weekend.
Their opposition will be a stong Cill Dara side who perhaps had the easiest path to the decider thanks to a walkover in the last-four.
