It's a celebration, but it's also so much more.
A celebration of the 20th anniversary of their first Canberra Raiders Cup premiership.
But also a celebration of the lives of old boys Paul de Dassel and Michael Thompson.
The two died in April and May respectively and the Gungahlin Bulls wanted to do something at their annual Old Boys day to not only honour their lives, but help others as well.
They'll wear a replica jersey from their 1999 triumph then they play Belconnen United at Gungahlin on Saturday and then auction them off with proceeds going to Menslink to help young men.
Sadly, de Dassel took his own life, while the circumstances surrounding Thompson's death are still unknown - but he had dealt with mental health issues.
Lachlan Wickham was part of that '99 premiership and was mates with de Dassel - or "Bobby Dazzler" as he was affectionately known.
Together they not only were the Bulls centres, but they also formed two thirds of a fearsome Red Faces act as well.
Wickham said what the Bulls were doing meant a lot to de Dassel's family, who were coming to Canberra for the weekend to be a part of it.
"Bobby was a really nice guy. Never had a bad word to say about anyone," Wickham said.
"Your typical country boy, lived to play footy and I think he came to Canberra to trial for the Raiders.
"With another mate of ours we won the Red Faces competition three years in a row.
"We used to have a Red Faces night at the club every year and each team had to put in three entries.
"Bobby was a pretty talented guitarist and he used to play the guitar and we'd pretty much bag everyone else in the lyrics."
Thompson was a hard-as-nails backrower.
He was the youngest of three brothers, who combined could've formed the prototype of the perfect footballer.
"He was a good heart, really tough footballer, that was just dealing with some mental health stuff," his brother Rob said.
"I guess like a lot of men, they don't tend to talk about it and they bottle it up. Organisations like Menslink are doing some fantastic things.
"He was a great loyal friend and brother. One person summed it up at his funeral, 'Between you three boys if we had've amalgamated you three we would've had the super footballer'.
"I had all the speed, my middle brother was the playmaker and Mick had that toughness and stature."
