Arran Brindle reckons a "great" Test is in store after Anya Shrubsole took two late wickets to leave Australia rocking at the end of day one.
Following Brindle's battling 68 as England were bowled out for 201, the tourists came out firing with the ball and reduced the home side to nine for two.
Shrubsole took both wickets to fall, that of Elyse Villani and Meg Lanning, and Brindle is hoping for more of the same tomorrow morning.
"If we do what we've done tonight I think we can have a really productive morning session," Brindle told ecb.co.uk.
"We want to go out there, hit our straps and bowl the areas we've talked about and create chances. There is a little bit in the pitch, obviously that extra bounce.
"I think it's going to be a great Test match."
England were in trouble at 32 for three when Brindle came to the crease but partnerships of 64 and 58 with Lydia Greenway and Natalie Sciver respectively dragged the tourists out of danger.
"As soon as you step on the field against Australia you know you are in for a big fight," said Brindle.
"Batting at five you can either come in and you are flying or when you are struggling, so you need to play to your strengths and try and build from there.
"You always want to start a series with a bit of time at the crease, see all the bowlers and to get a few runs was great.
"It was a bit of a bad time to get out, just before tea, because I think me and Nat (Sciver) could really have kicked on but the way it's turned out we've managed to get out there and take two wickets."
Brindle reserved special praise for Sciver, who made 49 on Test debut - a valuable innings considering England's perilous position.
"Nat showed what she's all about - really calm and collected at the crease, knows what she's doing. She's great to bat with," Brindle added.
For Sciver, it was a day to remember. Just hours after receiving her Test cap she was walking to the WACA wicket to help Brindle keep the rampant Aussies as bay.
"I was very excited," said Sciver when recalling the moment she discovered she would play at Perth.
"I found out yesterday so I had an evening to mull it over. I slept well actually.
"It's slightly disappointing we could not push on a bit further and get some bigger partnerships but runs on the board will help put pressure back on them.
"We are all buzzing (with the late wickets). Katherine (Brunt) and Anya have put in a really good six overs for us and really put the pressure back on them."
