Former Australia batter on BBC Test Match Special

This is why we play Test cricket because it can all happen late in the game and this is the most riveting time of play.

Cautious stuff from Nat Sciver-Brunt after that flurry of wickets for England. Defend one end, and attack with Sophie Ecclestone seems to be Heather Knight's modus operandi.

Australia happy to milk two runs off Sciver-Brunt's sixth over to a defensive field.

England have been fantastic but the last thing they'll want is niggly lower-order partnerships like Australia managed in their first innings.

It was a huge difference between the sides. Australia's last four wickets fell for 158 runs, whereas England's went for just 15.

That was missing a second set of stumps. Looked 'less' out than one Heather Knight declined to review earlier in Sophie Ecclestone's over.

England desperate for these last three wickets, but have to keep their composure.

A couple of balls later and Alyssa Healy is hit on the pad again by Sophie Ecclestone.

Given not out, but this time Heather Knight goes for a review.

This looks like a very hopeful call.

If England can bowl Australia out then we won't have that conversation about whether or not Australia declared at the right time.

Sophie Ecclestone gets on to go on with the arm which flummoxes Alyssa Healy and England offer an appeal which is turned down by Sue Redfern.

Heather Knight declines the chance to review. The right call.

Next ball Healy gets a bit of width from Ecclestone and she ruthlessly cuts it the boundary through point for four. Top shot.

England need to be tighter in the field here because every run here is crucial for Australia. This has turned into a really good game. I'm not sure which way this is going!

Change of bowling as Nat Sciver-Brunt, who is carrying a slight injury, gets a tap on the shoulder from Heather Knight.

Sciver-Brunt's first ball is punched off the back foot through cover by Alyssa Healy for four. Australia's stand-in captain is playing a good counter-attacking knock for her side here.

One thing that is noticable is that Healy is standing in line with her stumps so she is vulnerable to a lbw.

If Ecclestone can probe away and apply pressure, it might work because Healy hasn't found her rhythm yet.

Sophie Ecclestone continues and England's close fielders are surrounding the bat like flies round, erm erm, a sticky bun.

The left-armer spinner bowls some threatening lengths and Alyssa Healy edges the second ball but it dribbles through the slips.

Just one run from the over, but here's how Alana King got off the mark a little while ago.

England should be thinking about getting Australia 230 all out and they need to capitalise on this. It has turned from Australia being on top to England back into the game now.

This Test match is now the highest aggregate score in women's Test history. There has never been a Test match with more runs.

Kate Cross is running in with purpose and Alana King goes back in her crease to her fourth ball and wafts at fresh air. That got the crowd interested again.

Here's the third instalment of that trilogy of quick wickets for England.

Every single run right now is vital, it's chipping away at a lead that England don't want.

Australia bat all the way down the order so it's no surprise to see Alana King confidently whip Sophie Ecclestone's second ball of her legs to the boundary for four.

King happy to see off the rest of the over without too much alarm.

England have changed what Australia can do now.

They can force them to only set 250 which is chaseable and now Australia are surviving instead of dominating.

Kate Cross finishes the over with a couple of lose deliveries, and Alyssa Healy wallops one of the through the covers for four.

Here's the ball which Cross produced to get the wicket of Ash Gardner moments ago.

The danger for England is that Healy is a dangerous player who make it to 50 easily. But she has played some shaky shots and had a tickle of an edge and has no runs in the previous Test.

We know what Ecclestone can do...

Sue Redfern's on-field decision was correct. The ball-tracking technology shows it would have missed Alyssa Healy's leg stump.
