G'day Leslie,
For an informed answer I encourage you to post your question over on
Model Shipwrights (MSW), Armorama's naval modelling sister-site. You can use your Armorama/Kitmaker user name and password to login.
I'd take a gander at it though and say there are a few photo-etch (yes, seriously: photo-etch crew!) options available to you, but the blokes at MSW will be able to point you in the right direction.
Cheers
Rudi
p.s. what part of beautiful Tassie are you from?
