Andy Murray believes that his success last year has given him more confidence for 2013.
The 25-year-old won the US Open and gold at the Olympics in 2012.
"The last few years I got close but never managed to get over the final hurdle," BBC Sport quotes him as saying.
"Now that I've managed to do it, I hope that when I'm in those situations again I'll deal with them better. I probably just feel a little bit more relaxed than I normally do a few weeks before a slam.
"I prepared very well in Miami and trained hard to get myself ready for the new season, and I hope can be successful here [in Brisbane]."
Murray will take on John Millman in the second round at the Brisbane International on Thursday.
