A Dutch international with 49 caps between 1992 and 1999, he represented the team at UEFA Euro 1992 and the FIFA World Cups of 1994 and 1998, helping them come fourth at the latter.

[7] When Bergkamp left Inter for Arsenal at the end of the 1994–95 season, Jonk felt that his opportunities were limited as he neared the age of 30, and he went back to the Netherlands to sign with PSV.

[10] He was frequently injured, which caused the Wednesday fans to voice dissent about a clause in his contract which stipulated that he would automatically receive £7,500 per game, which he would miss through injury.

[10] Jonk made his debut for the Dutch national team as substitute, coming on in the 75th minute for Richard Witschge.

[14] While at PSV, Jonk was selected by Guus Hiddink for the 1998 FIFA World Cup in France, after being overlooked for UEFA Euro 1996.

With the appointment of Frank Rijkaard as the new manager after the 1998 World Cup, Jonk played only once more for the Netherlands in a friendly against Denmark on 18 August 1999.

After his career as a player, Jonk featured as a football pundit on NOS Studio Sport,[17] before returning to his childhood club Volendam as the board member for technical affairs.

[10] Jonk is a Catholic; while many of his Dutch teammates were raised in the church, he was the only one of his contemporaries to make the sign of the cross while playing.
