I used the FH560 fuse shown towards the bottom of the page at:
http://www.vehicle-wiring-products.co.uk/VWPweb2000/fuse-1/fuse-1.html
This has bolt-on ring terminals and takes a bolt-in strip fuse, available in
a variety of sizes.
The plastic moulding has survived unscathed forward of the firewall.
Don't know where you would get one in Oz.
Probably made in Taiwan!
Downside of CBs is a higher voltage drop than a fuse, which can be
significant in some circuits (eg some configurations of alternator field
current).
