Nathan Lyon admits he was nervous watching Australia's batsmen cop a battering on a Perth Stadium pitch that continues to shape the second Test against India.
A total of 11 wickets fell on day three while Aaron Finch, Usman Khawaja and Marcus Harris were all rattled by heavy blows from India's pacemen.
Finch, who retired hurt but was cleared of serious damage after being hit on his right index finger, remains in doubt to resume batting on Monday.
Australia will resume their second innings at 4-132, leading India by 175 runs, with Khawaja and Tim Paine having survived a fierce examination late in the previous session.
"The Indians have got a world class bowling attack ... we expect nothing less from their bowling attack," tailender Lyon said.
"I was a little bit nervous watching it out there but I'm a nervous character waiting to bat anyway.
"Just to see the good quality of Test cricket being played, that made me quite happy. It's exciting, gets your adrenaline going as a player ... there's nothing better than seeing good, hard Test cricket."
India's quicks would have been salivating at the sight of snaking cracks that have gradually opened up across the lively drop-in pitch.
Conversely, the visitors' batsmen will face a huge challenge batting last against Australia's pace battery of Mitchell Starc, Pat Cummins and Josh Hazlewood.
Indian quick Jasprit Bumrah said the pitch held no fear for his side, whose first-innings was propelled by a brilliant century from Virat Kohli.
"If you see the match, nobody has really gotten out on the crack," Bumrah said.
"The crack is just there, but it doesn't do a lot.
"It's only in the mindset, so we don't take that into consideration."
