Hey Matt,
Can't help with rudders etc in Bris, probably best to source in Vic or SA and ship up as will be right for a mossie.
Where are you in Bris?
Any plans on sailing through the summer or racing and where?
I will be sailing from Cleveland and Michael sails from Bribie and Humpybong at Redcliffe.
Would be great to meet up and sail together sometime.
Cheers,
