Seb started his career at Brisbane Strikers before spending last season playing in the Australian A-League with North Queensland Fury, where he made a handful of first-team appearances.
When the club went bankrupt at the end of the campaign, he decided to come to England to look for trials.
Just before he was about to fly home, in late August, he was contacted by Gary Bowyer.
After impressing on trial, he put pen-to-paper in October on a contract until the end of the season, with the club having the option of a further year which was taken up.
