you can see a pin prick of light but it's so tiny you're not sure if
it's just what you see when you look that hard at the dark:-) but by
well over a mile it's definitely in play & by 1 mile very clear.

Here the pleasure boat rules just require "visible" at 2 miles.

What brand of LED are you using?

There are some (pricey) LED lights made in the Netherlands, called LOPO
lights, that are certainly a lot brighter than a standard bulb. I first
noticed them about a year ago at a boat show and they appeared
dazzlingly bright even in an indoor setting with a tradeshow light
level.

You could probably get a "deal" on some if there isn't currently a
distributor in AUS.
