From Australian International Arms (AIA):

Australian International Arms have manufactured the 5th generation of Lee-Enfield, for target shooting, military match and sporting markets. However, unlike the 4th generation, this is not a ‘converted’ Lee-Enfield. The AIA rifles are redesigned with modern techniques

The below photo shows the current models on sale. They are all .308.

This photo comes from the Canadian company Marstar who sells them in Canada. The official AIA website is not very informative.

If you are not familiar with Enfields (from Wikipedia):

The Lee-Enfield was, in various marks and models, the British Army’s standard bolt-action, magazine-fed, repeating rifle for over 60 years from (officially) 1895 until 1956, although it remained in British service well into the early 1960s and is still found in service in the armed forces of some Commonwealth nations. In its many versions, it was the standard army service rifle for the first half of the 20th century, and was adopted by Britain’s colonies and Commonwealth allies, including India, Australia, New Zealand, and Canada.

The below photo shows what I believe to be are prototypes and are defiantly not sale at this point in time. I have read about AIA 7.62x39mm which suspect is what the below rifles are chambered in. They may in fact be using AK magazines! AIA only offers rifles in .308 at this point in time.
