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. Only eight earth rings are documented for the entire state of Victoria. Five of these are found in Sunbury. 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.
As you make your way to the cache you will pass the ring, which is surrounded by a fence. Do not enter the fenced off area and please be respectful of the land and area. This ring features the remains of a small stone cairn in the centre.
At GZ you are looking for a regular sized cache, please be careful of snakes and creepy crawlies. The cache is not hidden in amongst the car ruin. I wouldn't recommend looking for this cache during warm weather due to the risk from snakes and fires.
Please trade fairly and most importantly, have fun!!!
