Their mutual contentment also signified a good reason to add to their family and not long into their Australian adventure, they added a little "Braussie" boy to the family, Henrique.
 
"It was a breath of fresh air, being in Australia", he says. "I remember in my first season I saw players driving from training with surfboards on their cars going to the beach. It was just so relaxing and calm."
 
Juliana agrees it was a far cry from what she was used to in Brazil, in all aspects. "Like Cassio says about him becoming a man here, I also became a woman. I learnt to look after my family.
 
"I had a housekeeper in Brazil and so if we wanted chicken that night, we would ask for it. It was normal there. Here, I make my family dinner, I make them cookies - I love doing these things."
 
In their very South American way, both Cassio and Juliana say the reason Australia "won over their hearts" was because of the people - and the fact that there is so little judgement on how you live your life.
 
"In Australia, people go and sit in a park together, drink wine, have fun. Sometimes, if you do that in Brazil, people think you are poor or you aren't getting paid," Cassio says. "It's less about class, and status, here."
 
The normality of living in Adelaide was something they embraced, with Juliana taking the opportunity of having Cassio home more to go back to studying - something she gave up twice because of football moves.
 
"In 18 months I will be finished my degree in International Business and it will hopefully open the door for me to work in Importing and Exporting," she says with Cassio looking on proudly. 
 
He adds: "It's my time to support her so she can have something for herself."
 
For the now "Braussies", the decision to become citizens was an easy one, although initially inspired by a potential opportunity to play for the Socceroos three years ago.
 
"I was approached by my then coach Rini Coolen and Football Director Michael Petrillo and they said there could be some interest in using me as a left back for the national team, " he says.
 
"And if I was interested, they would help my family get citizenship.
 
"It didn't work out for me with the Socceroos", he acknowledges. "And I admit I did feel disappointed, but not for long. Because it gave me a great excuse to be Australian and I am so proud of that."
 
Cassio Oliveira was a kid from Rio with a dream. Now, as one of the A-League's most accomplished players, he looks back on his life with no regrets.
 
But how does such a player, one who as played in the top level in Brazil, won Adelaide United Club Champion twice, Player's Player of the Year, and spots in both PFA Team of the Year and most recently Adelaide United's Team of the Decade, define his biggest career highlight to date?
 
"Yes it's nice to win those awards but my career highlight has to be the friendships I have made over the years", he says. 
 
"The awards are great but the people I am still in touch with, from growing up in Brazil to people that I have met in Australia are all part of my career highlights and memories.
 
"And that is what I take with me beyond my career."
