The club, while not wanting to restrict classes racing at its Allansford circuit, wanted permission to only allow drivers and crew holding National Association of Speedway Racing insurance coverage into the pits.

Premier Speedway wanted the ruling to ensure all parties were racing and working in line with one set of safety standards and rules and it could therefore be protected from law suits.

Premier Speedway general manager David Mills said the club was disappointed with the ruling and was seeking advice on arrangements for this season.

"We could see where the opponents were coming from but from our point of view, the main point that was lost was we are not about stopping classes racing at Premier Speedway," he said.

"We are there protecting ourselves at the pit gate."

But the Australian Competition and Consumer Commission ruled the move would impact on speedway racing clubs which issued licences in competition with NASR.

ACCC chairman Graeme Samuel said the commission accepted there would be some benefit in having a national set of safety and racing standards. But the ACCC did not accept restricting access to only NASR licence holders would achieve that.

"While such bodies can host events at the notifying tracks, their drivers will also be required to obtain a NASR licence. This may reduce the attractiveness of competing licensing bodies and reduce their ability to expand their membership," Mr Samuel said.

The ACCC recognised benefits of a single controlling body for a sport which could develop minimum safety and related racing standards to be met by licensing bodies.

He said an industry code of coduct could be developed to achieve standards which would allow licensing bodies to demonstrate participants complied with the minimum standards, therefore giving tracks an effective risk management process.

"The ACCC recognises that the notifications may assist the tracks to implement risk management practices. However this must be balanced with the anti-competitive effect resulting from the exclusive arrangements," Mr Samuel said.

Premier Speedway, Murray Bridge and Brisbane speedways had lodged a joint application for permission to restrict access to NASR-only members, following the lead of Avalon and the Perth Motorplex, which had previously been granted access. The ACCC is now proposing to overturn its previous approval to Avalon and Perth tracks.
