Queensland stewards have emphasised the new three-hour arrival time for horses in feature races will be strictly enforced despite objections from trainers.
The state came into line with other jurisdictions on July 1 with all runners in races worth $100,000 or more having to be on course at least three hours before start time.
Three trainers have already been fined for late arrivals.
Chief steward Peter Chadwick met with trainers recently and told them the $100,000 threshold might change in the future.
Trainers raised the issues about the lack of tie-up stalls and float parking at some tracks which will need addressing to cater for more horses on course.
The fact Queensland trainers who bring horses from major centres such as the Sunshine Coast, Gold Coast and Toowoomba often face traffic problems was also raised.
Chadwick told the meeting the time rules would be strictly controlled and harsher penalties such as scratching could be applied.
He also said the potential of delays caused by traffic and breakdowns would need to be supported by solid evidence.
The issue of trained barrier staff travelling to country and provincial tracks has also been revisited.
The Queensland secretary of the Australian Trainers Association Cameron Partington said trainers had no problems with city barrier attendants but would support a move to have professional attendants who could travel to meetings throughout the state.
