Lleyton Hewitt's quest to be more unpredictable began predictably.

The South Australian took just 66 minutes to dismantle unheralded Israeli Dudi Sela 6-2 6-2 in a first round fixture at the Adelaide International.

Hewitt's comprehensive triumph was the perfect start to a new year in which the 26-year-old has resolved to become more unpredictable on court, refining his approach with new mentor Tony Roche.

Hewitt spoke pre-tournament of wanting to tinker with his tactics in a bid to grasp his holy grail, the Australian Open, later this month.

But in Tuesday night's performance before an adoring home crowd at Memorial Drive, it was hard to discern any real difference - the match was over so quickly.

The thrashing was distinguished by typical Hewitt traits: pressure and precision.

Hewitt's severe treatment of Sela's faltering service overwhelmed the 22-year-old Israeli, who lost the initial four games of each set in sliding to an inevitable loss.

Hewitt also served seven aces and won 90 per cent of his own first serve points in a polished display in his first tournament match in almost three months.

"It was perfect," Hewitt said.

"I got off to a good start and played pretty aggressively."

Hewitt said the wily Roche offered measured praise for his near-faultless performance.

"He said well done, he doesn't go over the top too much," Hewitt said of his new coach.

"It's a first round match so I have started the new year well.

"I think he was pretty happy with the way that I played.

"I felt pretty good with everything I am working on at the moment.

"I definitely still worked on areas of my game out there that I wanted to try and keep doing and take from the practice court onto the match court, and I felt like I was able to do that somewhat."

Other results on Tuesday included the toppling of eighth-seeded Frenchman Sebastien Grosjean by American Vincent Spadea, who won 4-6 6-1 6-3.

Australian Chris Guccione advanced to the second round with a 7-5 7-6 (7-5) triumph over American Wayne Odesnik but fellow Australian Alun Jones lost in straight sets to Russian Evgeny Korolev.

French second seed Paul-Henri Mathieu beat his compatriot Julien Benneteau 7-6 (7-2) 7-5, Finland's third seed Jarkko Nieminen disposed of Slovakia's Ivo Klec 6-2 6-4 and France's sixth-seed Jo Wilfried Tsonga accounted for Romanian Victor Hanescu 6-3 4-6 7-5.
