The atmosphere created by the Wellington Phoenix's newest fans on Sunday was, simply, awesome, spurring on the 'home' team as they played out a 2-2 draw with Western Sydney Wanderers.

Under a beaming Wollongong sun, positioned behind the goal posts, the Phoenix's Mexican cheer squad were eager to make their presence felt. The supporters - decked out in sombreros and national team jerseys - continued to chant, dance and wave Phoenix flags.

Then, a saxophone could be heard. Behind the instrument was Wollongong teenager Tomas Phillips.

Was Phillips allowed to bring a saxophone into the ground? That's up for debate. But the 17-year-old was having the time of his life. And he has since become a viral sensation.

"I brought down my saxophone to the previous game and I was threatened to be kicked out twice for playing it, which was really discouraging," Phillips said.

"But I persisted and I turned up to the game on Sunday with it, and they (Mexican fans) just loved it. I played the Mexican national anthem for them a few times and they were all getting involved and a couple of other songs which made for a good day.

"You could tell that the players loved it. They loved having the support behind them, not just people in the crowd watching but feeling the support behind them."

The wall of noise was exactly what has been missed at the Phoenix's first three home A-League fixtures.

Their losses at the hands of Sydney FC, Newcastle and the Mariners were compounded by a lack of atmosphere at WIN Stadium.

To be fair, it was understandable.

The Phoenix, stuck more than 2200 kilometres from home, arrived in the Illawarra and set up a temporary base. Due to COVID, they can't return to Wellington this season.

The area also boasts plenty of proud Sky Blues and Wanderers supporters, while our very own Wollongong Wolves were denied entry into the A-League in 2018.

But all of that doom and gloom was washed away last Sunday when more than 100 new Phoenix fans arrived by the busload.

However, the loud noise wasn't appreciated by everyone. In this COVID world, fans have been discouraged from singing and dancing at A-League games this season.

As a result, police and security kept a close eye on the group at WIN Stadium.

"It was a bit of a shame to see the police come over after about 60 minutes to tell everyone to sit down, while the RBB (Wanderers supporter group Red and Black Bloc) were fully up and about," Phillips said.

"It felt like they were trying to dampen everything ... but I think WIN Stadium [staff] have tried to be good with it all, to be fair."

The Mexican fan base seemed to emerge from nowhere, rocking up for the Phoenix's game against Sydney FC at Kogarah on February 8. They were there to cheer on one man, Wellington captain Ulises Davila, who is the only Mexican player in the A-League.

The Phoenix have embraced the supporter base, providing financial assistance to bus the fans down from Sydney to Wollongong last weekend.

Phillips, a passionate football fan, has also welcomed the Mexican cheer squad and loves seeing A-League action in his hometown.

"I'm a (Wollongong) Wolves fan and I go to a few games a season. And I also did a bit of journalism work, so I try to stay involved in the game," he said.

"Going to the first few Phoenix games, there wasn't much of an atmosphere, it's been a bit dead with the home support and the crowd. And then we saw the Sydney FC fans where all of the Mexicans came down and it all looked really good.

"I'm not sure who contacted them - I think it was the Phoenix who got them down there (to Wollongong) - and they had a big day out. It was a big coming together of the Mexican supporters and the Phoenix, and Wollongong supporters. It made for a good atmosphere on Sunday."

The fans also caught the eye of Wellington head coach Ufuk Talay, who said their support was "fantastic" after Sunday's draw.

"We're going to have 26 away games this season unfortunately without any home fans. The support that came down with the Mexicans behind the goal I think adds value to the team. And the boys need that backing sometimes from their supporters," he said.

"It's been great that they came down and I think they were at our Sydney game previously. WIN Stadium is a top stadium where the voice stays in the stadium, so I think they did a fantastic job supporting the players.

"It's great support, not just for 'Uli' but also the team. WIN Stadium is our home stadium, but there were probably more Western Sydney supporters at the game. Any type of support we can get, it plays a massive role."

For Phillips, he hopes that the vocal supporters show why A-League belongs in the Illawarra. The teenager, who lives five minutes away from WIN Stadium, desperately hopes to see the Wolves taking on Australia's best teams in Wollongong.

"Wollongong deserves a team in the top league, and I feel like this is a good opportunity for people to come out and show their support. With COVID and perhaps Wellington maybe not doing enough community engagement, I think crowds have been a little underwhelming. But it's fantastic to have them in the town and raising interest for the game, and league," he said.

"I've never seen the Wolves in the top league but my Dad has supported them since their existence, as have many other people in the community. I think having that (A-League) team is something that we're all trying to push for.

"I think it's (WIN Stadium) one of the best stadiums in Australia, to be honest. The capacity is around 20,000 and, even on Sunday, there were only a few thousand there but the atmosphere was so good. If the stars align, and the Wolves do get in the A-League, getting 10-15,000 fans like they do for the Dragons games would just be incredible.

"That's what we're all striving for, that would be the ultimate end game."
