Simon Danielli and Tom Court have agreed new deals to remain at Ulster until June 2012.
Tighthead prop Court, who won his first Ireland cap against Italy last year, arrived in Belfast in 2006 having previously played for Queensland Reds.
And the Australia-born 29-year-old admitted he never wanted to leave Ravenhill.
He said: "I am delighted and very, very happy. I have been honest from the start, I have been here for over four years, and I made it clear that I wanted to stay with Ulster.
"I am really pleased that everything is now sorted out, I feel very much at home here. I love the people, I love the rugby and I know this Ulster squad is developing in the right direction.
"There is some great young talent coming through and I am very positive about the team achieving success in the future."
Scotland winger Danielli joined Ulster in 2007 from the Borders, and believes the club are now on the verge of something special.
He said: "I am really pleased to be staying at Ulster, I consider it to be my home now and I am very excited about the next couple of years.
"I think we have a fantastic group of players and coaches, and I want to contribute to this team winning some silverware."
