The tax on cigarettes got even higher for jockeys Nash Rawiller and Jim Cassidy at Randwick on Saturday when both were fined $100 for smoking between races.

Cassidy said he had never heard of the rule prohibiting smoking but stewards produced rule 91 to close the case.

Stewards caught the pair when they were looking for Rawiller to question him over the unplaced performance of Boban in the Apollo Stakes and were told he was outside.

The riders were told the case came under the rule which says jockeys must remain in the jockeys' room once on course.

The fines amount to the equivalent of around five packets of cigarettes.
