'We had to grind it out'

Ireland 19-17 Australia

Ireland captain Claire Molloy speaking on ITV: "That was a tough match. We knew they were going to be physical so I'm really proud. We won the collisions and got the tries at the end.

"The resilience and resolve was there and we knew if we held in there we'd create the opportunities

"We had to grind it out and the crowd were behind us. It was was massive when we scored."

Elsewhere on day one

Holders England beat Spain 56-5 in the first match of the day, while four-time winners New Zealand came out on top against Wales, winning 44-12.

The fans rise as one to salute the Irish team.

It was tense all the way but they deserved to get their World Cup off to a winning start.

Sophie Spence's impact in the second half was huge.

Both packs really fronted up in the second period but Ireland won most of the crunching hits, each one cheered by the crowd who loved every minute of that.

Ireland are barely making any metres but they are keeping the ball...

And it's all over. The hosts start with a memorable victory!

Ireland 19-17 Australia

Ireland need to stand their ground here - Australia are coming for them.

After a quick drinks break and injury check-up, Ireland have a line-out on the halfway mark.

The Irish pack drive and drive. Possession is everything in these last few minutes.

Ireland 19-17 Australia

This is breathless drama.

Australia aren't giving up without a fight. They try and gain some territory with a touch-finder but it's charged down by Ireland and they steal the ball.

And then the Aussies steal it back! It's all too much.

Converted try - Ireland 19-17 Australia

Hilisha Samoa (con Hewson)

It's over!

Front-rower Hilisha Samoa twists and turns and taps down around the Irish defence.

Ashleigh Hewson slices over the conversion. Two points in it!

Ireland 19-10 Australia

This is such an open game now. Australia pile forward and they're inches from the line.

It's lift off for Ireland's World Cup campaign!

Australia's second try has brought the hosts to life.

Now they're playing with the urgency and sense of purpose we expected to see from the start.

They're looking comfortable in their own skins.

Try - Ireland 19-10 Australia

Sophie Spence

The referee thinks he can give it.

He checks.

Is it down? It's down! Ireland have a third try from another replacement.

Try review

Ireland 14-10 Australia

Ireland are 11 phases in and heading for the left-hand corner.

Another drive from the hosts. Ciara Griffin wriggles even closer to the line.

Is Sophie Spence down in the corner? To the TMO we go!

Ireland 14-10 Australia

Here come Ireland again, they're getting closer and closer to the try line.

But Australia snatch possession and clear out... it falls as far as Nora Stapleton.

They start again...

Ireland 14-10 Australia

The atmosphere is electric in Dublin now.

Ireland have a line-out on Australia's 22 mark and once again the hosts get down low and attempt to drive forward.

This time, the ball rolls out and Australia have the line-out.

Ireland 14-10 Australia

Ciara Griffin (con Stapleton)

They're over! The power and drive pays off and Ciara Griffin pounces.

Nora Stapleton lands the conversion with ease. Ireland are back in front.

Ireland 7-10 Australia

Ireland pump their legs and drive forward, inch by inch.

Are they over? There are bodies everywhere!

Ireland 7-10 Australia

Ireland finally make their way back into the Australia 22 and earn a scrum about five metres out.

They need to do something with this...

Try - Ireland 7-10 Australia

Shannon Parry

Grace Hamilton drives hard and Australia are inches from the line.

Wait for it... captain Shannon Parry crashes over with the pick and go!

Samantha Treherne has an easy conversion... but it's dreadful. She barely gets anything on it and it dribbles wide.

That could be really costly if Ireland hit back.

Ireland 7-5 Australia

Australia earn a penalty and Samantha Treherne kicks to touch to take them towards the Irish 22 line.

What can they do here...

Rebecca Clough takes the line-out well... they're pushing hard...

It feels like we're going to be camped out in the middle of the pitch for a while.

Neither side can make the break.

'Biggest roar of the night'

Ireland 7-5 Australia

Orla Bannon

BBC Sport Northern Ireland in Dublin

Marie Louise Reilly's line-out steal has brought the biggest roar of the night from the Irish fans.

Could it be the spark to ignite their second half?

Ireland 7-5 Australia

The crowd are fired up now. They're really getting behind the girls in green and it's helped - Australia have lost a line-out.

Can Ireland capitalise? They're still camped in their own territory.

Sene Naoupu makes an inviting run but she's stopped in her tracks.

Ireland find some room on the right but they're soon crowded out again.

Ireland 7-5 Australia

Ireland's defence holds firm and they earn a scrum in their own half.

Centre Jenny Murphy's had to go off injured, she's been replaced by Katie Fitzhenry.

Ireland 7-5 Australia

Rebbeca Clough - on as a replacement for the Australians - drives her legs and tries to charge forward but she's grounded by the Irish defence.

It gets really messy as Australia try to build up another attack, starting from the centre of the field. The ball is pinging about all over the shop.

Ireland 7-5 Australia

Australia force Ireland back into their own 22 before they eventually kick clear.

As the Wallaroos try and string together another attack, there's a handling error from Grace Hamilton and Ireland have the scrum.

Now the hosts kick forward into the Australian 22... but Samantha Treherne holds it up.

This is so close.

Kick-off

Ireland 7-5 Australia

Off we go again. Katrina Barker - Australia's scrum-half - boots us into the second half.

In case you missed it...

England 56-5 Spain

England got their World Cup defence off to a storming start with a 56-5 victory over world number eight Spain.

Here's what captain Sarah Hunter had to say about their 10-try win.

Half-time

Ireland 7-5 Australia

This was always going to be the closest contest of the day. It hasn't disappointed.

Ireland 7-5 Australia

The sun is blazing down in Dublin. It looks glorious out there.

Australia patiently build from left to right and gold shirts line up in attack.

But Ireland hold it up on the five metre mark and earn a scrum.

Ireland 'sucked into sevens rugby'

Ireland 7-5 Australia

Orla Bannon

BBC Sport Northern Ireland in Dublin

Ireland were energised by Muldoon's try but have got sucked into a sevens' style, loose kind of game - which is right up Australia's alley.

They have pace to burn out wide and showed it with Murphy's try.

The home crowd are nervous.

Ireland 7-5 Australia

There's no greater joy in rugby than seeing a hooker go on the charge down field. G'waaan, Cheyenne Campbell!

The Australian bulldozes through but the girls in gold are held up as Ireland hit them hard.

This is brutal.

Try - Ireland 7-5 Australia

Mahalia Murphy

Sevens-style showboating!

A quick line-out sees full-back Samantha Treherne send a looping ball over to winger Mahalia Murphy who steps Eimar Considine and steams over the line at full pelt.

The conversion is missed when the ball falls off the tee just as Treherne is about to kick it. Awkward.

Ireland 7-0 Australia

Australia waste their penalty chance. The line-out was a mess.

Ireland have possession but can't get out of their own half until they earn a penalty after a high tackle from fly-half Trilleen Pomare.

The Irish clear out.

Ireland 7-0 Australia

Australia want to get an immediate response and they earn a penalty for offside in a kickable position.

They go for the corner instead.

Converted try - Ireland 7-0 Australia

Larissa Muldoon (con Stapleton)

Ireland are inches from the line. It's a constant stream of pick and goes.

Finally... scrum-half Larissa Muldoon snipes and goes over! The crowd LOVED that.

Nora Stapleton lands an easy conversion between the posts.

Ireland 0-0 Australia

The referee stops play and goes to the TMO as he's spotted a potential infringement in the line-out.

He thought the Australian prop Hilsha Samoa might have taken out the Irish lifter, but after checking it a couple of times he's happy the girls in green were at fault for dropping their own player.

No foul. Australia earn a scrum in their own 22.

Ireland 0-0 Australia

Ireland are on the charge, they're 10 metres out from the try line.

Nora Stapleton feeds to her left but her pass has too much zip on it and not enough height so Alison Miller can only knee it and it goes into touch.

'Nervous start' for Ireland

Ireland 0-0 Australia

Orla Bannon

BBC Sport Northern Ireland in Dublin

This has been understandably quite a nervous start by Ireland.

The hosts had targeted a good start but they have barely been out of their own half so far.

The crowd chant 'Ireland, Ireland' to try and get them going.

Ireland 0-0 Australia

Ireland celebrate like they've scored as they overpower Australia at the scrum in their own 22. They really enjoyed that little battle.

The Irish try to clear their lines but get it all wrong and Australia push forward once again.

But now the hosts regain possession. As Claire Molloy attempts to run forward, she's smashed by Australia wing Nareta Marsters.

That looked painful.

Ireland 0-0 Australia

Sharni Williams finds a gap in the Ireland defence and dances through, but the Australia attack is continuously held up.

Trilleen Pomare tries to grubber-kick to a gold shirt cross-field but Ireland full-back Hannah Tyrrell gets there first.
