And Bias Boating who do online as well. Bunnings have them, think Mitre10 might too

Yep Bunnings have them black or white and two sizes.

Yes try Bunnings/Masters/Mitre 10.
They are component adopted for marine use, not made for it.
Just a tip, if I may, place a cup between the Perspex and aluminium as a spacer.

If you cant find any I can post a handful to you.
I buy a thousand at a time.
