In the weeks leading up to the final of Australian Idol 2006, Geyer was selected by both Mark Holden and former Idol judge Ian Dickson as their favourites for winning the competition.
On 12 November, Geyer received a second Touchdown from Mark Holden after his performance of Edwin Mc Cain's "I'll Be".
That same year Sony BMG dropped Geyer due to the under-performance of Rush.
He sang "I Don't Wanna Be" by Gavin De Graw for his elimination performance, and later performed the U2 smash hit "Beautiful Day" with Chris Murphy.
They became close friends and impressed the judges with their voices and their camaraderie.
Geyer portrayed the role of Ty Harper an aspiring musician who had dropped out of law-school and moved to Erinsborough.
Geyer worked with Neighbours drama coach Mike Bishop for four months to help prepare himself for the role and he took vocal lessons to work with his South African accent.
In April that same year Geyer released his debut single If You Don't Mean It which peaked on the ARIA Charts at #10.
