Symonston is named after Sir Josiah Symon, a lawyer, politician and one time Attorney General of Aystralia. He was also one of the founders of the Constitution of Australia, and apparently had a collection of more than 10,000 books - which seems a bit odd given the nature of the suburb.
There is not a lot in Symonston to be honest - unless you have a burning need to visit Geoscience Australia or the Therapeutic Goods Administration, or involuntarily get sent to the detention centre there.
The old Mugga Mugga cottage from the 1870s is, however, there. Unfortunately, it was not open when we were there, so I didn't get to go in - but the views from the front are still pretty impressive. Unexpectedly, there is also an olive grove apparently blessed by a greek goddess - again fairly strange given the surrounding, and several caravan parks...
Oddly Symonston felt a bit like 'the end of Canberra' although it is realistically quite close to the centre.
