Sam Groth has said that he has been on a "pretty amazing" journey after reaching the third round at the Australian Open for the first time.

The 27-year-old beat fellow Australian Thanasi Kokkinakis in five sets to book a meeting with another compatriot, Bernard Tomic, in round three.

The world number 82 told reporters: "The journey I've taken the last two years, the last 10 years, the last 20 years, it's a pretty amazing feeling.

"I feel like I'm in career best form and I'm where I'm at in the rankings for a reason. I'll come back firing on Friday. I have the opportunity to play in the second week.

"So if I can win another match and get in the second week, I feel like I deserve to be there. I'm a country boy. I always wanted to play on the big courts. That was my dream. Now I'm living that dream."

Groth, who holds the record for the fastest ever recorded serve, has only won one Grand Slam match coming into this event.
