Context paragraphs:
List of FIFA Confederations Cup hat-tricks: This is a list of all hat-tricks scored during FIFA Confederations Cups; that is, the occasions when a footballer has scored three or more goals in a single football FIFA Confederations Cup Finals match.  Scoring a hat-trick in a FIFA Confederations Cup is a relatively rare event: only 9 hat-tricks have been scored in 108 matches in the 8 editions of the FIFA Confederations Cup tournament.  As FIFA is the governing body of football, official hat-tricks are only noted when FIFA recognises that at least three goals were scored by one player in one match.

Australia national soccer team: The Australian national soccer team represents Australia in international men's soccer.  Officially nicknamed the Socceroos, the team is controlled by the governing body for soccer in Australia, Football Federation Australia (FFA), which is currently a member of the Asian Football Confederation (AFC) and the regional ASEAN Football Federation (AFF) since leaving the Oceania Football Confederation (OFC) in 2006.

2015 AFC Asian Cup: The 2015 AFC Asian Cup was the 16th edition of the men's AFC Asian Cup, a quadrennial international football tournament organised by the Asian Football Confederation (AFC).  It was held in Australia from 9 to 31 January 2015.  The tournament was won by Australia after defeating South Korea 2–1 in extra time in the final, thereby earning the right to participate in the 2017 FIFA Confederations Cup, which is to be hosted by Russia.  The win was Australia's first Asian title since their move from the Oceania Football Confederation (OFC) in 2006.  It was also the first time a men's team has become champions of two confederations, following Australia's four OFC Nations Cup titles: 1980, 1996, 2000 and 2004; following right after the Australian women's team won the 2010 AFC Women's Asian Cup 5 years ago.

2017 FIFA Confederations Cup: The 2017 FIFA Confederations Cup was the 10th FIFA Confederations Cup, a quadrennial international men's football tournament organised by FIFA.  It was held in Russia, from 17 June to 2 July 2017, as a prelude to the 2018 FIFA World Cup.

2010 FIFA World Cup qualification (OFC): The 2010 FIFA World Cup qualification for the Oceania Football Confederation (OFC) selected New Zealand to compete in a two-legged home-and-away playoff against Bahrain, the fifth-place team from the Asian Football Confederation (AFC) for a spot in the 2010 FIFA World Cup in South Africa.  (Oceania is the only confederation that does not have an automatic place in the finals.)  Its final round was the 2008 OFC Nations Cup.  Consequently, New Zealand is also considered the OFC Nations Cup champion, and represented the OFC in the 2009 FIFA Confederations Cup.

Krestovsky Stadium: The Krestovsky Stadium (Russian: Стадион «Крестовский» ), also called Zenit Arena, is a retractable roof stadium in the western portion of Krestovsky Island in Saint Petersburg, Russia, which serves as home for FC Zenit Saint Petersburg.  The stadium was opened in 2017 for the FIFA Confederations Cup.  Initially, it was planned to be completed by December 2008, which was changed to late 2011 and was scheduled to open in 2017.  As of May 2017, the stadium is 518% late and 548% over budget.  The stadium has a capacity of 68,134 people.

2023 AFC Asian Cup: The 2023 AFC Asian Cup will be the 18th edition of the AFC Asian Cup, the quadrennial international men's football championship of Asia organised by the Asian Football Confederation (AFC).  The tournament will involve 24 national teams, including that of the host nation, assuming the current format of the finals is maintained.

Northern Mariana Islands national football team: The Northern Mariana Islands national football team represents the Commonwealth of the Northern Mariana Islands in international men's football.  The team is controlled by the governing body for football in the Northern Mariana Islands, the Northern Mariana Islands Football Association, which is a member of the East Asian Football Federation (EAFF) and an associate member of the Asian Football Confederation (AFC).  The federation is not a member of the world governing body FIFA and so whilst the national team is eligible to enter AFC and EAFF-run competitions, they are currently ineligible for global competitions such as the FIFA World Cup and FIFA Confederations Cup.  As such, they do not have an official FIFA ranking.  However, the team have been consistently ranked as one of the worst teams in the world on the Elo ratings and are in fact, at July 2016 rated as the worst men's senior international team in the world in a ratings system that also includes a number of other non-FIFA teams.  Following the completion of the preliminary qualifying round for the 2017 EAFF East Asian Cup the team have won only one official competitive match against international opposition and have a goal difference of −78 in official matches.  The team have never qualified for the finals of a major tournament and beyond friendlies and qualifying matches, their only official competition has been in an exhibition tournament in the regional Micronesian Games in 1998, which they won, to date their only tournament success.
