These four sisters - Maureen, 27; Faye, 24; Helen, 22 and Trina, 26 - seem destined for the stage. With seven kids in their family, they learnt to sing through family jam sessions in their South Sydney home.
The girls are influenced by Destiny's Child and The Jackson Five. Having spent time as back up performers for Guy Sebastian earlier this year, the girls have had a lot of experience in the industry, but never secured that elusive record deal. They are hoping that will change with The X Factor.
On auditioning, Faye says: "We actually haven't done many auditions before and we thought, What is there lose? We'll just do our best and see what happens."
Mahogany impressed the judges with their performance of "Thank You" by Boyz II Men, and quickly progressed through the next rounds.
They are ready to get started: "We're looking forward to working with the incredible professionals on the show, performing and developing our identity."
The girls have put their careers on hold for The X Factor - both Maureen and Faye are primary school teachers; Helen works in retail; and Trina is a case manager at NRMA.
