Hamilton's epic trip to watch brother's race debut
The 2008 Formula One world champion, runner-up in the season-opening Australian Grand Prix on Sunday, told British reporters that he would be at the Renault Clio Cup race along with father Anthony.
He will then return to Malaysia for the grand prix at Sepang the following weekend.
"I am the closest person to him but even I cannot comprehend what it must have been like to have the difficulties he has had," said Hamilton of his 19-year-old brother, who has cerebral palsy.
"I'm so proud of him. I'll just head back to see his qualifying and race and then pop back out.
"It's cool. I will get to watch lots of movies on the plane."
Anthony Hamilton, who is manager to Force India's British rookie Paul di Resta, was also in Australia at the weekend.
