Hi Theo, good question. The short answer is yes, obviously there will be several stops that will only be able to access by seaplane or helicopter. Depending on the interest level and how many aircraft wish to participate will depend on each group size.
Something I learned from the previous round Australia trip is that it is difficult to get accommodation at some locations when five or six aircraft land in a small town, especially when you only booking the day before. As it is difficult to book in advance due to possible delays through weather conditions. Thanks for your question.
HI Theo, Tom Lockley here. Yes, landplanes can certainly join in for as little or as much as they like. Goble and McIntyre had a seplane only, so they were unable to use land airports. This meant that they had to moor their aircraft each night, and storms and tides were a huge problem: sometimes they got very little sleep, specially in NW WA where tides are extreme. I would be surporised if many seplane-only aircraft took part, for this reason.
Anthony Coleiro is preparing a pilot's handbook and it will describe light aircraft lading and accommodation facilities near the sites used by G & M. The idea is that the anphibians might land in the original spot used by G & M then fly to the land base overnight.
Can somebody with a land-based plane join this tour?
