What are the types of visitor visas that a non citizen can obtain for Australia?

There are some countries which have an arrangement with the Australian Government permitting the citizens of those countries to obtain an electronic visitor visa.  There are also a sponsored and a non sponsored visitor visa for which a hard copy of an application has to be lodged at an office of the Department of Immigration either overseas or in the case of renewal or a new visitor visa in Australia at an office of the Department of Immigration in Australia.
