Andre Russell only faced seven balls and Jason Holder one ball. I wonder if West Indies left 10 or 15 runs out there...?

It'll be spin from both ends. Roston Chase is on with his tweakers.

It's an important game for West Indies because they want to get in the top eight for the T20 World Cup next year. And it's absolutely vital for Australia.

Hosein may be a spinner but he's firing in 62mph deliveries an opening bowler in a club game would be proud of. The West Indies fielders are hopping around, trying to give the impression of drama.

Warner and Finch are watchful to start.

It's all mind games. There's no spin. They're just trying to mess with Davey Warner's mind.

There's a short leg in for Warner.

This all feels very testimonial. Kieron Pollard and Chris Gayle are standing at short leg and silly mid-off chatting away with David Warner.

Gayle eventually moves on to slip but it's still a very attacking field.

The players have made their way onto the field. Dwayne Bravo got a little guard of honour on the boundary edge from his team-mates.

Spinner Akeal Hosein is going to open the bowling.

I'm not sure if Chris Gayle will stay in the game. I think with all the runs, games, sixes and experience that he can pass onto the next game.

He is the type of person that won't lavish you with information but you have to go to him.

So Australia need 158 to win.

If they do it they will very likely go through to the semi-finals.

The only way the Aussies could be knocked out after winning would be if South Africa beat England by a very large margin.

I like to think Chris Gayle is the happiest player in the world. It is close between him and Jason Holder. They might be tied for first or first and a half anyway.

Chris is a top man. He has done so much in the game that he has afforded himself the hair, glasses and socks etc without too much critique.

Thanks Tom.

Was this the final time we say Chris Gayle on a cricket field for West Indies? There has been so much to digest over the years but his cricket career has been quite the journey.

So will Australia get the win they need to seal their place in the semi-finals?

Here's Matthew Henry to guide you through their chase.

Australia leg-spinner Adam Zampa, who took 1-20: "I just try and use the wicket to my best ability. I know my role in this team now. My job is to get wickets throughout the middle."

On the target of 158: "I'm pretty happy with this. It's hard to get a gauge - in general it's a pretty decent batting wicket."

That was quite the recovery from West Indies, who were 91-5 at one stage.

Australia will feel they have the required firepower in the locker to knock those runs off, but it's more than enough to make it competitive.

The last five overs went for 58.

Momentum is big in T20 cricket but I think if you asked Australia before the innings they would have been chasing 158.

It feels a little below par but it gives them something to fight with if they get a couple of early wickets.

That one isn't 111m but it is a terrific way to finish. West Indies have the momentum. Those sixes will lift the changing room.

And another!

A whirlwind finish from West Indies as Andre Russell hammers a low full toss back over long-on.

111m!?! That is enormous!
