His 1990 season was largely lost to a succession of injuries that restricted him to just 12 games, though he did play in Penrith's maiden Grand Final appearance (an 18-14 loss to the Canberra Raiders) and from there was selected, along with Panthers teammates Greg Alexander, John Cartwright and Brad Fittler, for the 1990 Kangaroo tour. Geyer played in 11 games on the Kangaroo Tour, scoring 4 tries and earning his first Australian test jumper when he was selected on the bench for the first test against France at the Parc de Sports in Avignon.
