You could win a double pass to the Miss Fisher's Murder Mysteries Costume Exhibition. It's on for a limited time from March 1 to June 1 at the National Trust's Old Government House in Parramatta Park, Sydney.

It's a chance to see amazing and sumptuous costumes featured in the hit ABC TV series that follows the adventures of the glamorous, independent detective, Miss Phryne Fisher. Many of these have never been on display before.

There are over 40 costumes on show worn by Essie Davis - who plays detective Phryne Fisher - plus costumes used by the very talented Miriam Margoyles (who plays Aunt Prudence) and Nathan Page (Detective Inspector Jack Robinson).

Why not step back in time and see a remarkable Australian world from another era? The costumes have been generously made available by costume designer Marion Boyce and Every Cloud Productions. Marion Boyce won Best Costume Design at the prestigious AACTA Awards for her remarkable work.

We have four double tickets for you to try and win. Entry is easy just email your name, address and contact number to comps.queanbeyanage@fairfaxmedia.com.au before 5pm on Thursday, March 20.

Please note only one entry per household will be accepted and winners are required to book a viewing session to the exhibiton in advance. Winners will be randomly drawn and notified on Friday, March 21.
