There were some raised eyebrows when Spiranovic opted to depart Western Sydney Wanderers for Hangzhou Greentown in June, rather than returning to Europe.
But the cultured centre-back, who won a German Cup and competed in the UEFA Cup during his four years with FC Nurnberg, insists there's no chance of him losing the lustre during the two-and-a-half year time span of his deal with his new club.
And he believes Socceroos fans will see for themselves over the next eight days in the FIFA World Cup qualifiers against 170th-rankled Bangladesh in Perth and then in Tajikistan five days later.
Many Australians have come and gone in China, with Shanghai Shenhua’s Tim Cahill and Spiranivic the latest to join the money-soaked competition.
Though it's the richest contract of his career, Spiranovic is adamant the level is exacting enough to make sure his footballing faculties remain intact, albeit with the occasional undulation.
“The level is unpredictable at times," he said. "It can be world class one minute and the next you see things that you might not see in a top flight European league.
"But with the players they bringing in and the money they are spending, it’s no surprise that standards are lifting
“I am facing some top players each week, It’s always a challenge and I feel like I am getting still getting tested and that’s the most important thing.
"I was happy at the Wanderers, where I had a year remaining on my contract, and it was going to take a good offer to get me elsewhere.
"It just felt right to go to China. It ticked all the boxes and so far it’s been good. I am playing regular football now and feel like I am in good place.
"Over the last few weeks I’ve played against some top quality forwards and that will keep me in good stead."
Spiranovic's three games so far have brought two wins, a loss and a rare goal.
His debut came in the 4-1 slaying of Tim Cahill’s Shanghai Shenhua and Hangzhou has climbed away from relegation trouble to 10th with six games remaining.
Spiranovic, who has become a mainstay at the back for Australia while the likes of Alex Wilkinson and Bailey Wright joust to partner him, said the experience of his previous stints in Germany and also Japan had helped him acclimatise to his latest adventure.
"You embrace the culture as much as you can ... it has its challenges but it’s nothing I didn’t expect, talking to the boys who have played there including Timmy of course.
"It’s a fresh start for me, as a foreigner playing there there’s a lot expectation but I am enjoying that.
"Who knows if I'll go back Europe… but I spent a good for years in Germany. I was learning then and when I moved to Japan and played regularly there (with Urawa Red Diamonds) and that was massive for my development."
Spiranovic admits to knowing little of Bangladesh or Tajikistan, but the Socceroos' back-up staff has been monitoring both closely and the players will get to see plenty of video footage before Thursday night at nib Stadium.
Having opened its qualification campaign with a 3-1 loss againgst Kyrgyzstan and a 1-1 draw against Tajikistan, Bangladesh is coming off a 0-0 draw in a warm-up against Malaysia on Saturday.
“By the time kick off comes we will be 100 per cent ready for what they bring,” he said. “But, as always, we will focus on ourselves first and what we need to do.
"We all hungry ... we all have a point to prove every time we come into camp and Ange (Postecoglou) does his best to keep that competitive environment, which is vital.”
