Dave Rennie is first to make some changes.

It's the hooker Tolu Latu and prop Taniela Tupou who make way for fresh legs.

It's a fiery start to the second half from Wales. They've come out at 100 miles per hour and will want to keep this tempo up.

Maybe Australia will tire as the game wears on.

Australia clear their lines, but Ryan Elias is a little wayward with the lineout ball and Australia opt for the scrum.

Wales are on the attack as Liam Williams makes a dart down the blindside.

This is promising stuff from the hosts.

Australia are first back out of the tunnel, Wales follow led by captain Ellis Jenkins.

Dan Biggar gets us back under way.

Australia have an attacking mindset and will run from almost everywhere.

Wales though have a man advantage and are ahead on the scoreboard so just need to keep accumulating points and keep that lead.

If Wales can get three points here and there early in the second half they can then open up a bit later on in the game and get their danger men like Louis Rees-Zammit and Josh Adams involved more.

I think you could describe that half as eventful, putting it mildly.

Tries, red and yellow cards, a few scraps.

Wales have not really got going in attack, save for Ryan Elias' try, and yet the find themselves ahead and, yet again, a man up.

Australia's discipline has been atrocious. They'd be leading comfortably if they could keep their discipline.

What an eventful half we've had here at the Principality.

Australia drew first blood with an Andrew Kellaway try before their number eight Rob Valetini saw red for a high tackle on Adam Beard.

Wales hit back with a Ryan Elias try, while both fly-halves have kept the scoreboard ticking over with penalties.

Time to take break, we'll be back shortly for the second half.

Wales get the penalty and Dan Biggar uses the old banana kick to get Wales a 22m lineout.

Wales cough up possession soon after and the referee blows the half-time whistle.

Liam Williams puts in a great kick through for Josh Adams to chase, but the crowd are furious as replacement Tom Wright drags the flying winger back by his collar in the chase.

Wales need to get Willis Halaholo involved more because he's such a clever player.

He's strong and powerful but is fleet-footed too and will cause Australia problems.

He's great in attack but is solid in defence too.

He's got his kicking boots on today.

Wales re-take the lead with just a couple of minutes to go.

What will Dan Biggar choose here?

He's playing it safe and pointed at posts as we edge towards half-time.

What a run by centre Willis Halaholo as Wales go on the attack.

But it's spilled by Aaron Wainwright as the number eight attempts to take the ball at pace.

Wales do go back for the penalty for offside.

Australia are back up to 14 now as Kurtley Beale returns from the sin bin.

The referee decides is was Andrew Kellaway that went in early and awards the penalty to Wales.

Kellaway is back on his feet and heads down the tunnel for a HIA.

We've had a nasty collision in the air between Josh Adams and Andrew Kellaway.

Both wings went for the high ball with Kellaway landing awkwardly on his back.

Could Adams be in trouble here?

The TMO is having a look.

That's a disappointing return for Wales.

Australia bring down the maul and it's their penalty.

Wales will be disappointed because they've handed Australia three points there.

They simply should not be conceding points when they have a two-man advantage.

We're all square... but maybe not for long as Australia are penalised at the breakdown after the restart.

Dan Biggar kicks to the corner.
