Edward Beatty/ie has been recorded as joining in the Volunteer Army on 25 jan 1864 to proceed to NZ via the "Brilliant" to participate in the NZ Maori/Land wars. Appreciate the wherabouts of this record. cheers penne
The National Archives of Australia is the archive of the Australian Government, and hence our records date primarily from Federation in 1901.
In the first instance I would contact the AWM Research Centre to see what records they have. You can contact them either at email@example.com or by lodging an inquiry using their online form at http://awm.altarama.com/reft120.aspx. Alternatively, their phone number is +61 (02) 6243 4315. If they don't have the information, they may be able to point you in the right direction.
I did a quick search for places you might begin your search. There is some information provided by the State Library of South Australia at http://guides.slsa.sa.gov.au/content.php?pid=76180&sid=594745, but curiously they do not know of any SA participants who enlisted (see the top left hand box on the page)... This suggests to me that they do not hold any service records from this period, but it may be worth contacting them to find out what resources they do hold.
I also found a document prepared by the Christchurch City Library on resources relating to the New Zealand Wars, which may provide information about what happened in NZ. http://christchurchcitylibraries.com/Heritage/WarsAndConflicts/NewZ...
Sorry I wasn't able to help on this occasion, best of luck in your search.
Looking at other's research on this topic, it looks as though all of these records are held at the New Zealand Archives. Have a look at the "Defending Victoria" website and you will find some details there. http://users.netconnect.com.au/~ianmac/waikato.html
It appears that Edward may have been the only volunteer from South Australia, though not born there. There is a lot of information in the newspapers of the day, and this article on the departure of the "Brilliant" http://tinyurl.com/736nols
You can see a full passenger list, including Edward, on the PROV website http://126.96.36.199/indexes/index_search.asp?searchid=42 Just search for the ship name Brilliant in 1864.
