READ NOWThe 23-year-old student and disability advocate was named as the next in line earlier this year when Senator Ludlam resigned after discovering his dual citizenship.
This morning, the High Court gave the green light to three new senators, but delayed making a decision on a fourth.
The other three senators to be replaced are Malcolm Roberts, Larissa Waters and Fiona Nash.
Former Australian Democrats leader Andrew Bartlett will return to the upper house, replacing Ms Waters as Greens senator for Queensland.
Business consultant Fraser Anning will step into the Queensland One Nation seat vacated by Mr Roberts.
The fate of NSW Liberal Hollie Hughes may need to be determined by a full bench of the court next week.
Until then, she will nominally take the coalition seat of outgoing cabinet minister and former Nationals senator Ms Nash.
The three confirmed senators will be sworn in on Monday ahead of the Senate voting on a new president to replace Liberal Stephen Parry, who resigned over his dual citizenship.
The position is tipped to go to Special Minister of State Scott Ryan.
