On 21 October 1872 the Mayor of Adelaide sent a telegram of congratulations to the Lord Mayor of London in recognition of this fast form of communication. The Governor, Sir William Jervois., stated that South Australia now possessed the key to the whole Australian continent because the centre of telegraphic communication must also mean the centre of the postal communication and as South Australia was already in control of the inland navigation of the continent and the centre of the railway connection between the eastern colonies and eventually the Indian Ocean, Adelaide must necessarily become the commercial centre of Australia.
