De Minaur, the world No.6, is preparing to lock horns with 10th-ranked Kazakh Alexander Bublik in the fourth round as he chases back-to-back quarter-finals at Melbourne Park.
The 26-year-old spoke after beating American Frances Tiafoe about how his weight of wins in recent years, including six career grand slam quarter-finals, had transformed his confidence for the better.

Natalie has noticed changes, too, and said, despite being 16 years older than her tennis star brother, that he inspired her with his determination and never-say-die attitude on the court.
โI see this resolve to really push himself, and I think thereโs this quiet confidence,โ she said.

โI think all of us, as humans, sometimes let those voices of doubt speak too loud, but heโs in a really good headspace. Heโs done the preparation, heโs healthy, heโs playing well, and heโs giving himself a pat on the back, allowing himself to accept how well heโs doing. He sees himself going further.โ
De Minaur has spoken about how he is trying to enjoy his success more and not rely on results for his happiness, a topic Natalie has discussed with him many times.
Someone else who has influenced that side of things is de Minaurโs fiancee, fellow player Katie Boulter. They are getting married at the end of this year โ and Natalie is thrilled for her younger brother.
โIโm biased, but Alex is such a good guy, and Iโm so happy for him because Katie is just the same in that respect,โ Natalie said.
โThey are so well-suited for one another. You can see how much they respect each other and support each other, and I think theyโre going to be incredibly happy together. I met Katie for the first time at the US Open in New York one year, and Alex was pretty excited to introduce her to me.
โWe were all feeling a bit nervous, but sheโs such a sweetheart, and I couldnโt be happier to see him marry someone as lovely as her.โ

Natalie and her husband Mark, who have three children, moved back home to Sydney 13 months ago after a seven-year stint in the United States.
It has been an eye-opener for her to return and witness de Minaurโs star and profile rising in Australia, even if her kids just view him as Uncle Alex, who has a strong and โplayfulโ relationship with his niece and nephews.
De Minaurโs family, like he is, are daring to dream that he could win a grand slam title one day, maybe as soon as this yearโs Australian Open, but Natalie is โuber proudโ of him regardless of what happens in the future.
โI think he represents tennis in a really positive light for younger kids,โ she said.
โHis kindness and generosity to start a foundation to support younger players [sums up who he is], just giving back to the sport. That was definitely something that he struggled with, and the family struggled with โฆ because itโs a really tough and expensive sport to break into on the international stage.

โAll this reminiscing is going to make me cry. Iโm so proud of him.โ
