The Twentieth anniversary of the relationship was a Twelve month celebration from November 2016-2017 and began with a Mayoral delegation from Busselton travelling to Sugito for 3 days celebrations. BASSCA purchased SUGIPYON, the Sugito Town mascot, who has since become a familiar sight around the city, and also published the Bridge of Friendship Book, a celebration of the sister city reltionship in words and pictures.
2006 was the 10th anniversary of the sister city relationship. Exchanges between Busselton Senior High School and 3 Junior High Schools in Sugito actually began in 1994, 2 years earlier than the formal relationship, when Rotary Club members from the respective towns arranged the student exchanges.
Two years later this arrangement was formalised with a sister city relationship.
