Sometimes referred to as Bora Rings, they have been formed by scraping off grass and topsoil, and piling it in a circular ridge around the outside. They measure between 10 and 25m diameter. All of the rings in Sunbury are on gently sloping sites. They are somewhat different to the Bora rings found in New South Wales and south east Queensland, which tend to be located in hidden, flat sites, and in connected pairs. The Sunbury rings first came to public attention, and first were investigated and described in the early 1970s, when archaeologist Dr David Frankel undertook a test excavation on one of the rings to determine their origin. Excavations revealed the remains of two small stone cairns, one in the centre and one on the edge of the circle, and a number of sharp stone plades or knives, which were possibly used in ritual scarification or circumcision ceremonies.
The rings have been interpreted as Aboriginal ceremonial sites, although there are no historical or ethnographic accounts of them being used as such. Members of the Wurundjeri Tribe Council have suggested the rings may be more than 1000 years old, based on the results of archaeological investigations. However, Elder Auntie Annette Xibberas acknowledged that the aboriginal people of Melbourne ...lost a lot of our knowledge with European colonisation, we only found out about these (rings) about 30 years ago.
The cache is located across the road from the ring which can be seen through the trees. The ring can be hard to pick out at certain times of the year due to the colour of the grass but it is generally identifiable by the lack of grass in it's centre. Better viewing can be obtained from the intersection of Riddell Road and Old Riddell Road.
Please do not attempt to access the cache from Riddell Road itself. Parking is available off Old Riddell Road. There is a steep cutting onto the road near the cache but there is no need to go near it.
I'm not sure how watertight the cache container is so I've left the log book and swaps in two seperate zip lock bags. Twist the lid to open the container.
Hope you enjoy my 43rd cache!
