Leinster have announced that their top-of-the-table Magners League clash against Munster at the RDS on April 12 is set to be an 18,500 sell-out.
Tickets have sold steadily in recent weeks and only a limited number of Leinster twin packs, also for the province's final home game of the season against the Newport Gwent Dragons, will be available from the Leinster Rugby Store in Donnybrook on Tuesday from 1pm.
Leinster boasted an average crowd of 11,900 in league games last season, albeit boosted by the 48,000 sell-out in the 'Last Stand' match against Ulster at Lansdowne Road and a then record figure of 27,252 in the 27-20 victory over Munster two months before.
The province has averaged 13,350 at home games at the RDS to date this season, which marks a hugely significant and impressive increase of 12.3%.
Leinster chief executive Mick Dawson said: "I would like to thank all our loyal supporters for turning out in such high numbers again this season in the Magners League.
"In reality these figures tell only part of the tale, though, as the support the team has received away from home in both the Heineken Cup and Magners League competitions has also been on the increase, not least at Stradey Park last weekend.
"We also enjoyed an average of around 18,000 in each of our three Heineken Cup pool games at home this season.
"The Leinster support has grown steadily in recent years throughout the province and nationwide and today's announcement is another timely boost for the playing squad and management ahead of a hugely important period in the season.
"We look forward to announcing details of our season ticket packages for next season over the coming weeks and hope to exceed the figure of 7,500 season ticket holders who committed to the province for this year's campaign.
"Our marketing team continues to work hard behind the scenes to ensure that the success on the pitch is matched by the entertainment value for supporters off the field of play for the remaining two games of the season and beyond."
