Stone axes were important tools for cutting wood, striping bark, felling saplings, cutting food gathering honey, and many other uses. A good stone axe had to be tough and shock resistant so that it did not shatter on impact. Mt William stone (Greenstone) was an ideal metamorphic rock, and was traded widely. Mt William stone could be ground to a razor sharp edge which set the Mt William people ahead in terms of skill and sophistication, and their monopoly of it gave then considerable bargaining power.
Not all types of stone can be used for making tools. The best stone types are rich in silica, hard and brittle, such as quartzite, chert, flint, silcret and quartz. These types of stone were quarried from outcrops of bedrock, or collected as pebbled from stream beds or beaches. Many flaked stone artefacts found on Aboriginal sites are made from stone types that do not occur naturally in the area. This means they may have been carried for long distances. 
Victorian Aboriginal Heritage Register
Aboriginal objects and heritage places are irreplaceable, non-renewable resources and can include traditional and spiritual sites of significance. The Victorian Aboriginal Heritage Register (VAHR) was established by the Aboriginal Heritage Act 2006 is an important administrative tool and holds the details of all known Aboriginal cultural heritage places and objects within Victoria, including their location and a detailed description. Places or objects are recorded by cultural heritage advisors on forms which are approved under the Act. The Victorian Aboriginal Heritage Register is not a publicly accessible register because it contains culturally sensitive information. Registered Aboriginal Parties (RAPs) play a key role in the protection and management of Aboriginal cultural heritage. The Register holds information of each Registered Aboriginal party, their area of responsibility and contact details. 
The Aboriginal Heritage Act 2006 requires that the discovery of Aboriginal cultural heritage places or objects on any public or private land in Victoria be reported to Aboriginal Affairs Victoria - see http://www.dpcd.vic.gov.au/indigenous/aboriginal-cultural-heritage/information-for-landowners/reporting-a-possible-aboriginal-place-or-object
If you are the custodian of a Victorian Aboriginal object or place you are encouraged to document it on the Victorian Aboriginal Heritage Register by contacting Aboriginal Affairs Victoria to arrange to complete the form located at http://www.dpcd.vic.gov.au/__data/assets/pdf_file/0003/35607/Victroian_Aboriginal_Heritage_Register_Form_Sept_2008.pdf.
How to care for and register Aboriginal objects and heritage places is further explained via an 11 minute video available at http://cv.vic.gov.au/stories/the-aboriginal-object-collection-at-dunkeld-museum/
