The Australian Grand Prix will once again get the season started in March, while Azerbaijan makes its debut as European GP host in June.

Race organisers confirmed earlier in the week that the Australian GP would open the 2019 campaign on March 20, after the race had originally been penciled in for early April.

In other changes, Bahrain switches from the fourth race of the season to the second, with the Malaysian Grand Prix, which was the second race of the current season, moving to October where it slots in between races in Singapore and Japan.

There are sure to be a few eyebrows raised with the decision to host the inaugural European GP in Baku, Azerbaijan on June 19, the week after the Canadian GP, and on the same weekend as the Le Mans 24 hours.

A four-week summer break has been accommodated between the German GP on July 31 and the Belgian GP on August 28.

Fears that the new 21-race season would run into December have not come to fruition, with the season-ending race in Abu Dhabi set for November 27.
