The 23-year-old hopes a return to Memorial Drive and his hometown tournament will prove just the tonic ahead of the Australian Open.
"It's nice to be back home and chill out and not have the stress of hotels and travelling around where you don't know your way," the world number three said earlier this week.
"To be able to sit back... I enjoy playing here, the weather, this is where it all started as well. I have a lot of mates come out here."
Oblivious to the field at Memorial Drive, the former world number one is just focusing on his own game.
"Actually I wouldn't have a clue who's playing," he said. "I'm just worrying about my own game. At the end of the day I think I'm playing well enough at the moment to go out there and put everyone under a lot of pressure. "For me this is about preparing myself as well as possible for Melbourne in three or four weeks' time.
"By January 17 I want to be hitting my peak but I feel Adelaide and Sydney this year is going to give me great preparation for that."
Hewitt knows runaway world number one Roger Federer is the benchmark this season but says he does not fear the Swiss.
"I can definitely beat him, yeah. But it's not going to be easy and I think I know as well as anyone, he's definitely the man to beat out there at the moment," Hewitt said.
"There's no point worrying about him (Federer) right at the moment. He's not playing here in Adelaide or Sydney and I if can get the number two seeding (at the Open) I won't have to worry about him until I play a Sunday night final at the Aussie Open.
"There's plenty of other good players out there you've got to be very wary of, so you don't just want to focus on one particular guy but obviously you're going to have to try and do something different if I do come up against him."
