JQ and Hayman Island

[Justin L]

I noticed that Hayman Island was on JQ's booking engine so selected a dummy flight in October for Sydney-Hayman Island which came up with the following schedule.

Sydney-Hayman Island
11:50 AM Sydney - 14:20 PM Hamilton Island JQ 846
14:45 PM Hamilton Island - 15:45 PM Hayman Island JQ 2100

11:50 AM Sydney - 14:20 PM Hamilton Island JQ 846
15:30 PM Hamilton Island - 16:30 PM Hayman Island JQ 2112

Hayman Island-Sydney
9:05 AM Hayman Island - 10:05 AM Hamilton Island JQ 2105
13:50 PM Hamilton Island - 17:10 PM -Sydney JQ 849

12:00 PM Hayman Island - 13:00 PM Hamilton Island JQ 2113
13:50 PM Hamilton Island - 17:10 PM -Sydney JQ 849

12:15 PM Hayman Island - 13:15 PM Hamilton Island JQ 2101
13:50 PM Hamilton Island - 17:10 PM -Sydney JQ 849

I can't find this on the JQ PDF schedule (which hasn't been updated since its expiry on 29MAR09) and am not familiar with the region, but would the Hamilton Island to Hayman Island services be a flight, if so an A320 or are JQ codesharing on a smaller flight? Or perhaps a codeshared boat service, given that the duration is one hour even though the islands are close? The Hamilton Island-Hayman Island vv leg can also be booked as a standalone booking.
