triton.vg was the site of Australian numismatist Jon Saxton. Due to health issues he sold his collection in 2015 in Noble Numismatics auction 108.

Jon Saxton's Australian predecimal coin website ceased to operate some time in 2020 or 2021. An archive can be accessed at Web Archive.

Coin Curiosity and The Sandpit both have good references on Australian predecimal coins.
