The 2008 world champion secured the 20th pole of his Formula One career in the season curtain-raiser at Albert Park in Melbourne, but had to settle for a third-placed finish behind McLaren team-mate Jenson Button and second-placed reigning world champion Sebastian Vettel in his Red Bull.
It was disappointing for Hamilton not to carry on his good form from qualifying on Saturday into the race as Button beat him off the line at the start of the 58 laps and remained in charge throughout.
However, the Briton was staying positive afterwards and, having congratulated both Button and his team 'for such a great result', he is now looking to ensure he crosses the line first in future races.
Speaking to Sky Sports F1 in the paddock, Hamilton said: "While it's a bit disappointing not to have been able to convert pole position into victory, I'm not downhearted.
"Yeah, it was a bit of a tough day, but we have plenty of races ahead and lots more opportunities to score points.
"Although it was quite a tough race, it is still quite positive for the team to come here with good pace, so hopefully we can take that on to the next race.
"We showed we have a very quick racing car, so I'll just re-focus now, get my head down and look to the next race.
"The world championships are all about consistency, and that's what I'll be aiming for."
