Big Artie Beetson — whose fondness of a meat pie is almost as legendary as his deeds with football in hand — is probably the greatest forward in Australian rugby league history, but his legacy is greater than the premierships he won with Balmain and Eastern Suburbs. Firstly, he’s the godfather of State of Origin, the interstate series between New South Wales and Queensland that’s the pinnacle of the code. And secondly, he became the first Indigenous person to captain Australia in any sport when he skippered the Kangaroos in 1973. Beetson's big frame, pure speed and brilliant ball skills won countless games for all his teams. His off-loading and attacking workrate broke the mould for front rowers and changed the way they played the game.

Beetson's rugby league career began with Redcliffe in the Brisbane Rugby League competition between 1964 and 1965. After winning the club's player of the year award in 1965 as well as the Brisbane Rugby League premiership with them, he moved to Sydney to play in the New South Wales Rugby Football League premiership with the Balmain club. The 1966 NSWRFL season was his first and he gained selection for the New South Wales team and played in that season's grand final against St. George at second-row forward. Beetson was also selected to make his representative début for Australia against England and set up the first two tries. He represented Australia again at the 1968 Rugby League World Cup, playing at prop forward in the win against France in the tournament final. Beetson then played with Balmain, with a spell in England with Hull Kingston Rovers in 1968.

After the 1970 NSWRFL season Beetson left Balmain to join the Eastern Suburbs club where he would stay from 1971 to 1978. He possessed great strength and toughness, a surprising turn of speed for a big man and was unequalled as a ball player. His skill as a footballer was matched only by his skill as an eater, earning nicknames such as 'Meat Pie Artie'. He was known and immortalised by his performance of eating 11 hot dogs before a gala dinner for the Australian team in 1973. Beetson captained Eastern Suburbs to the 1974 and 1975 premierships. During this period Beetson also continued playing with distinction for Australia and in 1974 he was named as Rugby League Week's player of the year. During the 1976 NSWRFL season, Beetson captained Eastern Suburbs to victory in their unofficial 1976 World Club Challenge match against British champions St Helens in Sydney. This Easts team would go down as one of the greatest club sides in rugby league history.

While still playing in Sydney for Parramatta, Beetson achieved further immortality as captain of Queensland in the inaugural 1980 State of Origin game, won 20–10 by Queensland on 8 July. He capped off that year with a man-of-the-match performance in the Eels' 8-5 Tooth Cup Final win over Balmain. Beetson returned to Queensland for one final year of playing with his old Redcliffe team in 1981, where he also captain-coached the Datsun South Queensland side to a 59-3 victory over Papua New Guinea. He also captained Queensland for the final 'traditional' interstate match in 1981 and at the end of the season the Dolphins were beaten in the final minute of the grand final by Southern Suburbs.

Beetson's coaching career began while still playing for Easts in 1977. He was captain-coach of Redcliffe in 1981 and that season was appointed coach of the Queensland State of Origin side, taking them to repeated series victories over New South Wales from 1981 to 1984. Beetson also coached the Brisbane rugby league team in 1981. He had a brief, but unsuccessful period, coaching Australia in 1983 before returning to coach his former club Eastern Suburbs, from 1985 to 1988, being named Coach of the Year in 1987. Also in 1987 he received the Medal of the Order of Australia "in recognition of service to the sport of Rugby League".
