The pilot was attending a fly-in to display his aircraft. Because he was concerned about the length of the strip he was endeavouring to touchdown at the threshold. During the final approach, he became aware that the airspeed was reducing below the optimum and applied some power, however, the aircraft struck the ground heavily about 10 metres before the strip threshold. The pilot applied full power and carried out a go-around. As a result of the ground contact the nosewheel was torn off. The pilot was advised of the situation by ground observers and elected to divert to Parafield. During the subsequent landing the nosegear leg collapsed.
