Despite repeated conversations about F1 returning to Adelaide, with the Australian Supercars championship still using a shortened version of the track, Marshall explained that utilising the street circuit again is no longer possible.
"We don't have the ability to put together a street circuit which would be suitable for Formula One, so the only option for the grand prix to come to South Australia would be at The Bend," said Marshall, via whichcar.com.au.
"To bring quality events to South Australia that promote economic activity and get our economy moving again is exactly what we're looking at."
The Bend is the second-longest permanent racing venue in the world - behind the Nordschleife - at 7.7km, which is 0.7km longer than Spa-Francorchamps.
Although the circuit currently only holds an FIA Grade Two licence and not the Grade One certification required for F1, should the need for a temporary change of venue arise, the situation could be swiftly dealt with.
"The answer is we will throw our hat in the ring and throw it again and again and again until there is a real opportunity," said track managing director Sam Shahin.
