Lleyton Hewitt has accused Tennis Australia of not doing enough for its players and said he may not play in the Davis Cup tie against Belarus in April.

Hewitt, who has only missed two Davis Cup ties since 1999, said playing for Australia was no longer his top priority.

"This year the majors are the most important things to me," said Hewitt, who won his first round match against American Paul Goldstein at the SAP Open in San Jose.

"I'll play the (Davis Cup) ties on their merits and on how my body is, and to where they fit into my schedule," he said. "I'll approach each tie differently."

Hewitt, who missed Australia's Davis Cup win over Switzerland last weekend citing an ankle injury picked up at the Australian Open, said he was still unhappy Tennis Australia had opted not to make the courts at the Open faster.

"It doesn't suit Australian tennis players," Hewitt said.

"In the United States, their officials speak to (Pete) Sampras and (Andre) Agassi about the courts and balls.

"It's disappointing to have no impact at all. They always say it's going to be done and nothing happens."

Hewitt said Australian players weren't getting the support they desired from Tennis Australia.

"I'd love all the Australian players to get backing," he said.

"I don't think they are doing a great job for tennis in Australia at the moment."
