Supercars is running through 2019 calendar scenarios with teams and media partners as it edges closer to finalising its schedule.

The championship is working to lock in its calendar for next year with talks well underway to secure contracts with both new and existing events.

Supercars expanded to 16 events this year following the elevated status of the Formula 1 Australian Grand Prix to a championship round and the addition of the The Bend Motorsport Park round in August.

The length of the 2019 Supercars schedule is up for discussion with championship CEO Sean Seamer stating ‘it is very hard to predict’ at this point in time.

However, Supercars is hoping to unveil its calendar as early as the end of September instead of the October reveal of its 2018 schedule last year.

As previously reported, Queensland Supercars teams are pushing the category to amend its schedule for next season amid calls the current calendar is ‘bordering on being unsustainable.’

“We have said we want to get the calendar out a little earlier this year and we are working with the teams and our media partners to run through some scenarios, but we hope to have something to announce in September/October,” Seamer told Speedcafe.com.

Two events on the current schedule have reached the end of their current multi-year agreements, namely Barbagallo Raceway, Perth and Phillip Island in Victoria.

Discussions to secure an extension with Barbagallo Raceway owners WA Sporting Car Club, Tourism Western Australia and Supercars kicked off last month during the Perth SuperSprint.

Amid contract talks the circuit aims to conduct a complete resurface in January next year.

Likewise it is understood conversations have been held between Supercars and Phillip Island regarding a new deal.

The famous circuit has proved a mainstay on the calendar despite regularly attracting small crowds.

The prospect of a race in Asia also remains a possibility with Seamer confirming that negotiations are ongoing with promoters.

Supercars has long targeted a push into the Asian market with a series of Memorandum of Understanding agreements already signed with several countries.

Singapore is understood to be the most likely possibility if a deal can be reached with promoters to feature on the bill at the Singapore Formula 1 Grand Prix meeting.

Seamer met with F1 owners Liberty Media at the Australian Grand Prix in March.

“That (talks with Asian promoters) is ongoing and to be honest we are taking a position of talking about what we have done rather than what we want to do,” he added.

Meanwhile, a host of existing Supercars events have one year remaining on their contracts including Sandown, Winton, Symmons Plains, Townsville and the Gold Coast.
