Australian midfielder Sebastian Pasquali has made his professional debut for Ajax's reserves in the Eerste Divisie.
Pasquali, who swapped Melbourne Victory for Ajax in November 2017, started for the reserves against Fortuna Sittard.
He was brought off after 58 minutes, with the Dutch giant going down 2-1.
Jong Ajax compete in the second division, the level below the Eredivisie.
The 18-year-old was unable to play for Ajax in the 2016/2017 season because of a protracted wait for his international clearance.
Pasquali has been on the bench for Jong Ajax three times this season.
The Wangaratta City junior has previously featured regularly for Ajax in the Under-19 Eredivisie and UEFA Youth League.
