Source for Secondary Mirrors in Oz/NZ ?

Just obtained a 16" F4 Dob. Wow a big step up from my old 8".

It is a home made job with a overly large secondary on a dogs breakfast of a spider (mind you it works).

Where would I source a good secondary to replace it in Oz/NZ ? Needs to be ~3.1" I estimate.

why not try Surplus Shed-even though they are US based- they may have something that you can use? usually the price is right too

telescopes & Astronomy in South Australia have a 70mm secondary for a
A$220. I'm sure Bintel or any of the others could get you one.
