No chance of long-standing season opener becoming a night event, according to extended contract.
Melbourne is guaranteed its place as the starting point of the Formula One World Championship's annual calendar, it has emerged.
Local media Fairfax has revealed Melbourne's new race contract until 2020 stipulates the season-opening slot for the race around Albert Park.
"We have clauses in there about (it being) the first race of the season," Australian Grand Prix Association chief Andrew Westacott said.
"The contract stipulates in various legal words about Melbourne being the first race and it being a day race.
"It's also in the agreement that there's no artificial light, so it's not going to go to a night race," he added.
There had been rumours that Australia could be relegated to a date later in the season, with the race's former host Adelaide having closed the championship throughout its Grand Prix tenure in the 1980s and 90s.
