Western Australian Adam Voges says his Test career is as good as over after losing his spot in the side during Australia's series loss to South Africa in November last year.

The 37-year-old had a poor run of performances with the bat and was dropped for Peter Handscomb after the innings loss in the second Test in Hobart.

"I'm done in terms of international cricket. I can probably acknowledge the fact I'm not getting back in the side," Voges told Fairfax.

"I'm realistic enough to understand my performances weren't up to scratch in my last few Tests and we lost those games which means there is always going to be change.

"It's always disappointing to get dropped or left out of the side, but there was only one person to blame and that was me."

If Voges' career is indeed over he will be remembered as one of the best ever batsmen from a statistical standpoint, with his amazing average of 61.87 second only to Sir Donald Bradman for a batsman with more than 20 innings.

The 20-Test veteran made his debut in 2015 against the West Indies and make his maiden Test ton in the same match.

His high-score of 269* was also achieved against the West Indies, with three of his five Test centuries coming against the side from the Caribbean.

"Being such a late starter it was good to get an opportunity at all, because two years ago I probably thought I was never going to play Test cricket," he said.

"So to be able to play 20 Test matches and get that Baggy Green I worked so hard for over a long period of time is something I'll look back on very fondly when it all finishes up."

Voges was named as the captain of the Prime Minister's XI for their one-off T20I match against Sri Lanka next month, in what looks to be his final match on the international stage.
