Usman Khawaja has launched a stunning rebuke of the Australian selectors claiming their selection policies are hurting the team.

Khawaja told ABC Radio he thought the selectors constantly changing the team was causing instability.

"They never used to do it before, I'm not really sure why they do it now," he said.

"It creates a lot of instability in the team I reckon, going in and out for everyone.

"You hear things like 'the players are playing afraid' or whatnot, but that's what happens when you drop players all the time. We've been doing that a fair bit lately.

"I know as captain of Queensland, I try and avoid that as much as possible; players I pick in the first game, I try to stick with them as long as possible, because they'll always be the best players on the park.

"For some reason it seems like lately in Australia, the best players always seem to be the next guy in, which I don't totally agree with."

The 30-year-old played an important role last Summer but was overlooked for the Border-Gavaskar series in March and has only played one game for the national side since January 22.

Khawaja said the constant chopping and changing has not helped his development, particularly in Asia where his struggles are obvious.

"[It's] very hard to develop your game and play some consistent cricket if you're not getting consistent opportunities overseas, which I haven't been getting," he said.

"It's frustrating but I've just got to focus on what's in front of me. I'd love to win an Ashes series – it's something I haven't been able to do yet."

Khawaja is expected to be recalled to the Australian line-up for next month's Ashes series after enjoying plenty of success in the two previous summers.
