Mr Boulcott said he allowed "at least half a truck" in between the vehicle he was driving and two cyclists prior to coming across the group Mrs Farrelly was in.
Yolande Savage, who was riding directly behind Mrs Farrelly, said she saw her stand on her pedals and turn her head.
Mr Boulcott's truck had given her a fright and caused her to wobble slightly just before the collision.
All of the cyclists who gave evidence said they couldn't hear Mr Boulcott's truck as it approached and Ms Savage said she first knew of it when she saw it in the corner of her eye.
"It was beside me and then I saw him hit Jane."
Coroner Gordon Matenga said there were two areas of consistent differences in evidence presented by the cycling group and that of Mr Boulcott including their formation while riding and the distance between the truck and the group as he tried to pass.
The inquest concluded yesterday after two days of evidence and Coroner Matenga will consider the evidence.
