Answer by taking a quote from the following article:

Giacomo Costa (14 December 1919 - 22 January 2000) was an Italian Australian professional wrestler best known by his ring name, Al Costello. Costello was the first professional wrestler to be nicknamed "The Man of a Thousand Holds" because of his innovative and very technical style. Costello was the creator and original member of the tag team The Fabulous Kangaroos, whose "Ultra Australian" gimmick complete with boomerangs, bush hats and the song "Waltzing Matilda" as their entrance music, existed in various forms from 1957 until 1983. Costello was either an active wrestler, or a manager in all versions of The Fabulous Kangaroos.

For years, Al Costello had been working on an idea for a new tag team; he even knew who he wanted for a partner: a wrestler he had worked with some years ago named Roy Heffernan. Because Costello and Heffernan had lost touch over the years, the idea remained dormant until Costello toured Hawaii in 1956. Costello mentioned his idea of an "Ultra Australian" tag team to fellow wrestler, and future promoter, Joe Blanchard. Blanchard happened to be a good friend of Roy Heffernan and knew he was working in Stampede Wrestling at the time. Blanchard put the two in touch with each other, and Costello was soon off to Calgary, Alberta, Canada to join Heffernan and finally make his tag team a reality. Costello and Heffernan debuted as "The Fabulous Kangaroos" on 3 May 1957 for Stu Hart's Stampede Wrestling promotion in a match against Maurice LaPointe and Tony Baillargeon. Only weeks after that first match, The Kangaroos were working with the top tag teams in the promotion. After working in Stampede for a while, The Fabulous Kangaroos started to travel across the United States, headlining shows wherever they went due to their ability to rile up crowds with their heel (bad guy) tactics. On one occasion in August 1958, The Kangaroos, or "Kangaroo Men" as they were billed, nearly caused a riot in Madison Square Garden during a match against Antonino Rocca and Miguel Perez; the fans began to throw fruit and stones at them. After the match ended without a decisive winner, the promoters stepped in, turned up the arena lights, and played the National Anthem to stop a potential riot. This was a common tactic used at the time by the New York promoters in order to prevent riots and help the heels leave the arena unharmed. Later that year, Costello and Heffernan started working for Dory Funk's NWA Western States promotion based in Amarillo, Texas. Here, The Kangaroos won their first title as a team when they defeated Pepper Gomez and El Medico to win the Texas version of the NWA World Tag Team Championship on 17 November 1958. Their first title reign was short lived, however, as Gomez and Rito Romero defeated them to regain the titles two weeks later. Between 1957 and 1965, The Kangaroos wrestled in the United States, Canada, Asia and select tours of Australia and New Zealand. They worked for such companies as Capitol Wrestling Corporation (the future World Wrestling Entertainment), Championship Wrestling from Florida, NWA Ohio, the Japan Wrestling Association and the World Wrestling Association in Los Angeles, California. The Kangaroos never forgot their roots and continued to work in Canada off and on through the years; in addition to Stampede Wrestling, the team also worked for NWA All-Star Wrestling based in Vancouver, British Columbia. Costello featured in a National Film Board of Canada short subject La Lotta/Wrestling/Le Catch. Their stint in NWA All-Star Wrestling was the last time Costello and Heffernan teamed together. In June 1965, The Kangaroos lost to Don Leo Jonathan and Jim Hardy and then split up. Heffernan had left Australia to tour the world in 1953 and wanted to return to his homeland, while Costello was determined to remain in the United States for a while longer. Heffernan returned to Australia and began working for World Championship Wrestling (the Australian version, not the North American wrestling federation) under booker Jim Barnett as a singles wrestler. Costello was originally supposed to return to Australia as well and work for WCW, but those plans never came through. Instead, Costello remained in the United States and kept working in the tag team division, never seeking a career as a singles wrestler. Costello began wrestling for Georgia Championship Wrestling, where he teamed up with Louis Tillet to form a tag team known as "The Globetrotters"; a name that played off Costello's Australian and Tillet's French heritage. The Globetrotters defeated the Mysterious Medics in the finals of the Georgia NWA World Tag Team Championship but only held the titles for a week before losing them to Kurt and Karl Von Brauner on 4 February 1966. After this, the Globetrotters broke up due to differences in their approach to tag teaming. Costello then moved to the NWA Mid-America territory near Nashville, Tennessee. In Mid-American, Costello teamed with Herb Welch to win the Mid-American version of the NWA World Tag Team Championship, which they held for just over 2 months. While still working in Mid-America, Costello began to team with Karl Von Brauner, who used a "German Nazi" gimmick despite being American. Under the management of "Playboy" Gary Hart, Costello and Von Brauner were billed as "The Internationals"; the team was later managed by George "Crybaby" Cannon. The Internationals worked mainly in Tennessee and Texas for NWA Western States. In Texas, Costello and Von Brauner won the Texas version of the NWA World Tag Team Championship, a title Costello and Heffernan had held in 1958. The team was also billed as the first NWA American Tag Team Champions, titles that were also recognized by World Class Championship Wrestling in addition to the Western States promotion. The Internationals lost the American Tag Team title to Fritz and Waldo Von Erich on 21 February 1967. Kurt then decided to go back to teaming with his storyline brother, Karl Von Brauner. After the Internationals broke up, Costello returned to Australia to visit friends and relatives and to recuperate after many years on the road. On his way back to the United States, Costello had a stop over in Detroit, Michigan, where he met Cleo Williams. The two fell in love and married shortly afterwards, remaining together for the rest of Costello's life. In 1967, Al Costello reformed The Fabulous Kangaroos, this time teaming up with Ray St. Clair. The team had been touring non-stop for about six months when St. Clair was forced to retire due to knee problems. A few months after St. Clair retired, Costello found a new man to don the bush hat: Don Kent. Kent, who was from Michigan, adopted the Ultra-Australian gimmick (but retained his American accent) and the two formed the third overall and second most well-known version of The Fabulous Kangaroos. Costello and Kent teamed together on a regular basis from 1968 until 1974, approximately the same amount of time that Costello spent teaming with his original partner, Roy Heffernan. Costello and Kent continued in a tradition that was reminiscent of the original Kangaroos; when a federation needed a new tag team title, The Kangaroos were brought in and acknowledged as champions upon arrival instead of holding a tournament to determine the champions. In 1967, the Japanese federation "International Wrestling Enterprise" (IWE) brought The Kangaroos in as the first Trans-World Wrestling Alliance World Tag Team Champions. They held this title until 10 January 1968 when IWE mainstays Toyonobori and Thunder Sugiyama beat them for the gold. Over the years, many more title reigns came from various promotions all over the globe. In Canada, The Kangaroos were the first Eastern Sports Association International Tag Team Champions. In the World Wrestling Association of Indianapolis, they held the WWA World Tag Team Championship twice. In addition to winning titles all over North America, Costello and Kent also made appearances for the World Wide Wrestling Federation (now known as WWE). The Kangaroos frequented NWA Detroit, where they held the Detroit version of the NWA World Tag Team Championship for most of 1971. By the end of 1972, The Kangaroos began working for Nick Gulas' NWA Mid-America. In Mid-America, they held the local version of the NWA World Tag Team Championship, the Mid-America version, on three occasions. After a match at Cincinnati Gardens, an enraged fan took a fire extinguisher off the wall and threw it at Costello and Kent from the balcony of the Gardens. The extinguisher hit Costello in the hip, damaging it so much that he needed hip replacement surgery later that year. The fan was arrested, served 15 days in jail, and fined fifty dollars for damaging the fire extinguisher. The hip injury left Costello unable to wrestle, and The Fabulous Kangaroos split up once again. Costello had a full hip replacement and was forced to retire from active competition. CANNOTANSWER

How did they perform?

Only weeks after that first match, The Kangaroos were working with the top tag teams in the promotion.
