Nothing to get the juices flowing just yet. It's a cagey start by both teams which is perhaps understandable. This is a game neither side dare lose.

Well, we knew there would be lots of Tunisia fans and there are. The Al Janoub is draped almost completely in red except for a small contingent of yellow in one lower-tier corner.

Australia are used to the feeling of an "away crowd" though - 16 of their 20 matches in World Cup qualification took place abroad, largely because of Covid restrictions back home.

Pantomime atmosphere. Cheers from the crowd every time Tunisia touch the ball. Jeers when Australia have possession.

It's probably the first game I've been to where there is an overriding sense of one set of fans taking over. It's a sea of red from the Tunisia fans. But these are the atmospheres you want to play in, it's absolutely phenomenal.

It's like an away game for Australia. There are Tunisia fans in red everywhere you turn.

Game number 21 of this World Cup is under way.

Right, lads. Please, please, please...not another 0-0 stalemate.

Australia manager Graham Arnold: "It's going to be a great, exciting game for the boys. It's going to be an electric crowd with a great atmosphere. A unique occasion.

Message to Australia fans: "We're here to put a smile on your face and we'll do everything we can to put that smile on your face. We know we have the support of a lot of fans back home and we're here to do them proud."

It's fast approaching 9pm in Sydney. The bars are rammed and millions are watching on television across the country. Australia need to take something from this match to stay alive and this is a chance for the Socceroos to give football in Australia a real boost.

The difference between making the knockout stages or not is taking your chances. Tunisia didn't take them against Denmark but I was impressed with their performance.

There is huge support for Tunisia at this World Cup.

There are an estimated 30,000 expats living in Doha and many are sporting their colours during the tournament.

Australia's fans are expected to be heavily outnumbered in the Al Janoub Stadium in Al Wakrah, where Tunisia's fans occupy both ends of the ground.

Nobody gave Australia any chance against France so to get that one out of the way, especially with the performance in the first 20 minutes, sets a good platform coming into this one.

I found former Australian international and ex-Leeds and Liverpool winger Harry Kewell in the media centre earlier.

We had a chat about the Australian team, how he thought today's game would go and what the feeling is around the country at the moment.

Kewell said it was going to be a "really tough" match. He was impressed by Tunisia in their opener and thinks they have a strong defence.

Australia's pace out wide could be their weapon, he adds, but it is a "young squad looking ahead to the future a little bit".

Australia are extremely hard-working but they are short of quality to go with their effort.

Tunisia showed against Denmark that they are a really well-organised team, and I can see them using their nous to edge this.

Sutton's prediction: 1-0

Australia have not won a match on the World Cup stage since defeating Serbia 2-1 in South Africa in 2010.

Meanwhile, this is Tunisia's sixth World Cup. They have never advanced past the group stage. This could be historic for the North African nation.

I was at the Khalifa International Stadium yesterday covering the 1-1 draw between the Netherlands and Ecuador (hopefully not the same today) and I spotted a pair of Aussies.

"You're a day early for the game and you're at the wrong stadium," I told them.

Andrew, the Liverpool fan, laughed and said they had come to explore the area and try to sort tickets for today's match.

He and his friend Daniel, who both work together, are from Melbourne and had only secured tickets for the opening defeat to France but are staying in Qatar for the whole group stage.

"A big game against Tunisia," Andrew said.

I just hope they got tickets...

Today's match is taking place at Al Janoub Stadium, about 22km south of Doha, and near Al Wakrah, towards the coastline of Qatar.

It's one of the venues which supporters have to travel out of the city centre to reach and you can only get here via a bus or car.

I left at around 8am local time to get here and there weren't many fans around when I arrived.

Speaking to supporters from all over the world in the last week, they have found the Metro system very easy and enjoyable to use but this is one of the stadiums that has been more of a struggle to reach.

However, Tunisia had strong support in their opening match and they have been present all around Doha so we're expecting them to arrive in numbers.

How many come for Australia will be interesting to see. The DJ has just played Kylie Minogue.

Australia went down 4-1 to holders France in their opening match, while Tunisia played well to secure a point against Denmark.

This should be a decent game. Both teams need a win to give themselves a chance of reaching the knockout stage.

Australia's qualification campaign lasted more than 1,000 days and covered 10 countries, with 16 of their 20 matches taking place abroad due to Covid-19 restrictions at home.

Having made it to Qatar the long way round, the Socceroos are desperate to avoid an early exit.

Lose to Tunisia and they're following Qatar out of the door.
