A number of Google references take you to adverts for the MV Kilkie, a small tourist boat in Sanctuary Cove, Queensland AUS. When you jump to the link you are presented with a detailed list of its venues and facilities plus a short description of the origin of the name.
Here is the text from one of their "Gold Coast" adverts:
M.V. Kilkie, is a 'Heritage Listed' ferry vessel, built in the 1950's. This lovely timber vessel is licensed to carry upto 40 passengers in ferry mode, although 25-35 is most comfortable for cruising the Coomera River and surrounding waterways. Kilkie runs from Sanctuary Cove Marina, depending on season and numbers, providing quite and relaxing cruise options.
Kilkie has an amazing history of service, both on the Gold Coast, Brisbane River and Maroochydore where she has carried thousands of happy passengers over the years. This vessel is ideal for small groups and parties, as well as having been a reliable ferry, servicing the entire Coomera, Sanctuary Cove, Coomera Waters and Coomers Shores areas,MV Kilkie has also serviced the Sanctuary Cove International Boat Show for many years, carrying hundreds of commuters to and from the show from many locations throughout the Gold Coast.
Seems that KILKIE is an aborigine word for a specific bird and the boat is named after the bird.
