Australia's youngest Olympian at the London Games, diver Brittany Broben, leapt into medal calculations with an impressive 10m platform semi-final performance on Thursday.
The 16-year-old schoolgirl qualified third for Thursday night's final, with teammate and close friend Melissa Wu ranked fourth.
And the Australian duo refuse to believe standout Chinese diver Roulin Chen has the gold all but around her neck.
"It's never sewn up," said Wu.
Chen was the top qualifier with 407.25 points - a whopping 47.35 points ahead of next best, Canadian Meaghan Benfeito (359.90), followed by Broben (359.55) and Wu (355.60).
"There are a lot of nerves but I have been controlling them pretty good at the moment, so hopefully I can do that tonight," Broben said.
Asked if a medal was possible, she replied: "I have no idea, I'm just going to go out there and give it my best."
But Wu believed Broben was well placed entering the final.
"I think it's amazing how she's doing," Wu said.
"She's diving really well and she seems really confident and is really enjoying the experience, I'm so happy for her."
