It was a tough loss for the Aussies to kick off their World Cup campaign with no batter or bowler standing up against a strong Kiwi side. With no pass marks throughout the group, there will be pressure on some of the players to keep their spots in today's match against Sri Lanka in Perth.

The good news for Australia is that the fast bouncy wicket will suit their Test seamers while putting the Sri Lankans on the back foot. Sri Lanka though is coming off a win against Ireland by nine wickets in their most recent match.

The good news for the Aussies is that Mitch Marsh is back bowling giving the Aussies another all-around option, after we saw Marcus Stoinis bowl four overs against the Kiwis.

The pressure though will be on Pat Cummins in this match after going for 46 runs against New Zealand and averaging 33.40 with the ball over the last twelve months.

With Kane Richardson on the bench and Nathan Ellis knocking on the door, there are certainly questions about whether choosing a Test lineup for T20 cricket was the right call.

The key to beating Sri Lanka will be in getting the match-ups correct and the following are five of the most important.

David Warner v Wanindu Hasaranga

37 balls, 60 runs, one wicket, average 60.

The right-arm leg spin of Hasaranga is key for Sri Lanka and he showed that in the most recent match against Ireland where he took 2/25 from four overs. He is the most important bowler in the Sri Lankan lineup and can offer some handy runs in the lower order.

Warner though has loved facing him in the past with Warner having the ability to sweep both traditionally and reverse. If Warner can get through the powerplay he will be able to up the run rate as the spinners including Hasaranga comes into the attack.

Glenn Maxwell v Maheesh Theekshana

27 balls, 53 runs, two wickets, average 26.50.

Another man that loves facing the spinners is Glenn Maxwell who will likely look to use the reverse sweep and switch hit against Maheesh Theekshana who is the second of Sri Lanka's mystery spinners.

With the ability to spin the ball both ways, Theekshana is incredibly difficult to face although if there is anyone to take it down it's Maxwell.

His strike rate of 196 against the spinner is immense and if Maxwell can come in a little later rather than in the powerplay he should be able to take full advantage.

Aaron Finch v Chamika Karunaratne

22 balls, 24 runs, no wickets, average n/a.

The pressure is currently on the Aussie captain after yet another failure at the top of the order against the Kiwis. There was one massive shot over mid-wicket though which looked like the Aaron Finch of old so we may see a small resurgence against Sri Lanka.

At the top of the order again it's likely Finch will be facing Chamika early on and in the past, he has struggled to score against him making just 24 from 22 balls.

Perhaps the answer is to push Finch back down to number four again where he looked good against England only weeks ago.

Josh Hazlewood v Dasun Shanaka

25 balls, 30 runs, two wickets, average 15.

Hazlewood has been Australia's most improved short-form bowler over the last few years and he continues to prove it with every outing. The good news for Australia is that he has a good record against the Sri Lankan captain which should put the Aussies on track for victory.

Shanaka though does like to take Hazlewood for boundaries though having hit him for 24 runs through boundaries of the 30 total. With Hazlewood taking more of a role in the death overs he may well need to add to the 14 dots he's bowled to Shanaka in the past.

Adam Zampa v Charith Asalanka

16 balls, 18 runs, two wickets, average nine.

Adam Zampa has been Australia's best bowler as of late, with 13 wickets this year alone, and a best of 3/16 against India earlier in the year. With Asalanka being one of the most dangerous Sri Lankan batters averaging almost 25 at a healthy strike rate.

With Asalanka likely batting at four, he's likely to come out just as Zampa comes into the attack after the powerplay. From his 16 balls faced against Zampa, he's only scored two boundaries while getting out twice. It's yet another matchup that Zampa comes out on top of.

The Australia v Sri Lanka match is set to begin at 10 pm AEST 7 pm local time in Western Australia with the match likely to finish in the early hours of the morning for most Australians.
