The 17 year-old hopes years of globetrotting will stand him in good stead after being handed a wildcard for the Australian Open.
Alex De Minaur works hard during a two-hour session on the court under the hot midday sun.
He's no stranger to gruelling, sweaty days like this. whether here in his native Australia or on the other side of the world.
"After sort of five years the whole family moved to Spain. We spent there eight years. Then we came back here for another three and just moved back. So we've been back and forth a couple of times."
The Sydney-born teenager has made the most of his intercontinental life.
He's fluent in Spanish, French and English.
His Spanish-Uruguayan restaurateur parents infused the young tennis star with an international flavour.
"Wherever the country I was in, I would speak the main language of the country outside of the house and inside the house we would speak the opposite language, but now English has sort of taken over."
Although still officially based in Alicante, in Spain's southeast, it's Australia where De Minaur feels most at home.
The teenager hopes to one day emulate the likes of former men's world number one, Lleyton Hewitt.
"That's obviously the goal, to be able to represent your country in Davis Cup. I couldn't think of a better thing to do."
And the Wimbledon junior finalist appears on the cusp of big things.
De Minaur made a stunning run through qualifying in the Brisbane International tournament where he upset 2015 Sydney runner-up Mikhail Kukushkin.
A wildcard entry to the Australian Open now puts him in illustrious company to appear in a grand slam as a teenager.
"It would be unbelievable to be able to go far in a slam but I'm just going to take things slowly."
