Lewis Hamilton lost out to Sebastian Vettel in Melbourne after higher tyre wear early in the race prompted him to pit first and gave his Ferrari rival the chance to leapfrog him at the stops.
Hamilton called on his team to focus on how the W08 uses the Pirelli tyres, and Mercedes motorsport chief Toto Wolff said there were lessons to be learned.
"It's personality-building," said Wolff of the defeat. "You just lose some and you win some. We have been very fortunate in the last three years that we won most of the races.
"And now it's about accepting that here Ferrari beat us. We will come back stronger. We didn't have great testing and we didn't have a great Sunday, but we will leave no stone unturned in order to win more."
Though Mercedes has dominated the last three F1 seasons, Wolff insisted his team had never been complacent about the threat from other teams so the Melbourne defeat was not a shock.
