The Czech star had to fight off a comeback from the world no.46 to win in three-sets 6-1 1-6 6-1 on Friday evening. 

It was a packed house at Pat Rafter Arena with the last two remaining Australians in the women's and men's singles draw took to the court. 

The Croatian-born player had been having a dream run in Brisbane and became the first Australian women's player since Jarmila Groth to make the quarterfinals. 

However, it wasn't the start to the game Tomljanovic wanted to the match as she was broken early on in the opening set and never recovered. 

But a pep talk to her coach, Goran Prpic, in the break turned everything around for the 25-year-old as she blasted her opponent and dominated in all aspects across the court. 

The crowd's excitement grew with the possibility of a come from behind victory on the cards for Tomljanovic as she took the second set in just 25 minutes. 

"I lost the momentum a little bit, the rhythm in the second, and I think she just stepped in the court a little bit," Pliskova said. 

"She tried to be more aggressive, and she was just going for her shots, especially the backhand."

However, the come from behind victory wasn't meant with the world No.7 punishing the Australian for her mistakes and finished the game the same way she started. 

Pliskova finished with an impressive 27 winners and 14 aces. 

She now faces Croatian Donna Vekic in the semifinals on Saturday night with the other semifinal between Lesia Tsuenko and US Open Champion Naomi Osaka.
