It�s all part of their latest acting roles at Playlovers Theatre in The Wardrobe by Sam Holcroft.
Set over a 530-year period, it tells the stories of various young people who seek refuge or comfort in the same wardrobe between 1485 and 2015.
From the last days of the Wars of the Roses, through English Civil War brutality, paranoia of the Plague and the heartbreak of World War I conscription, right up to modern-day complications with social networking, the play seamlessly weaves humour with moments in history that ultimately depict the loss of innocence.
Bianca plays Sarah, a 17th century serving girl, while Maddison plays Matilda, a parliamentarian child during the Bolton Massacre.
�Sarah is from the time of the Black Plague,� Bianca said.
�She�s opinionated but also very caring and willing to do anything; even risk her life to save a friend.
�One of the hardest things is learning an English accent for the role.�
Maddison describes her character as a gentle and caring person who is also brave.
�Matilda and her two brothers are left to fend for themselves inside the wardrobe,� she said.
�It will be challenging performing inside such a tight space but it will be interesting to see how it turns out.�
The two Frederick Irwin Anglican School students have been involved in theatre for the past seven years, appearing in more than 20 local productions.
The evening also includes the play Following the Black Sheep which explores the inner workings of a family just after the end of World War II.
