Australian Test spinner Matt Kuhnemann says he was 'never worried' by bowling investigation

Australia's Matt Kuhnemann insists he was "never worried" about the possibility of a suspension while being investigated for a suspect bowling action.

The left-arm spinner was reported by match officials and investigated by the International Cricket Council following an impressive 16-wicket Test tour of Sri Lanka.

Kuhnemann was required to undergo biomechanical testing in Brisbane to prove his eligibility and lift his ICC-imposed suspension.

The investigation revolved around whether the Queenslander extended his left elbow beyond 15 degrees.

But the investigation revealed the majority of the Test star's deliveries fell under 10 degrees.

The 28-year-old, speaking publicly for the first time since being cleared, said he was never fazed by the investigation.

"I was never really worried about the whole thing," he said.

"I accepted the process and moved on with it ... I think it's the life of a professional sportsperson these days.

"People might doubt you and what not, but it's how you take it.

"Over 100 professional games and never got questioned. Before the incident and after it, I have never been more confident in my ability as a cricketer at the moment.

"I've bowled millions of balls in my career. I never had doubt prior to the Test [series], [and] it was never going to change my point of view.

"At the end of the day, I had to follow a process. The umpires had to follow a process, [too]."

Kuhnemann revealed he was in the changerooms with his Australian teammates when he learned his bowling action had been reported.

But the challenge did not dampen his spirits after what was a career-best Test series.

"When it first happened there was definitely some shock, when I found out the news," Kuhnemann said.

"My next question was, 'What was the process and what did it look like?'.

"I was very grateful for the support that Cricket Australia and Cricket Tasmania provided me through that time.

"I accepted the process and it was very straight forward and simple, so I was happy to get it done as soon as possible.

"I was always confident I'd be fine," he continued.

"It gave me 10 days to rest and let my thumb heal; it's not very often you get a break in the middle of the season.

"It was a chance to let my body recover because I'd bowled a fair bit before that Test series in Sri Lanka."

The bowling sensation remains hopeful he will be able to secure selection for Australia's Test tour of the West Indies in June, but for now is focusing on performing effectively in all conditions.

"It's tough when you've got the greatest off-spinner ever in front of you," he said of Nathan Lyon.

"I am very fortunate to play alongside 'Gaz' in conditions that suit spin bowling.

"I love the art of spin bowling. I am trying to get better in every single condition in the world. If it's England, if it's Australia, a sub-continent, I love the challenge.

"For me, if I can contribute to help win games for Tasmania, that should help my case."
