Maybe get really serious about it and think about obtaining a small shipping container full of foam board. Then resell it in Australia. Make enough to retire and then fly all day long!
The shipping costs to Australia regardless of what you put in the container might kill that ambition.
Full disclosure...I'm speaking from experience as I do sell foam boards in Australia.
I'd had the discussion with Gilman Brothers in the USA about landing stock from the US. Gilman's are the original manufacturer of foam board and during that discussion we talked about the freight costs as being prohibitive towards importing product into Australia. Gilman's most likely manufacture a number of the foam boards in the US and they may "whitelabel" them under different brands.

At the time it cost around $10K to land an "empty" container in Oz.
We weren't talking about foam for planes but for large signage and other commercial applications because the use of foam boards for scratch building RC planes is only a small part of the market in Australia.
Over the years my business had tried to get the quality to a point that satisfies the Aussie market uses and as part of that progress there has been some consideration to the guys building planes.
On a personal note I'm a boomerang thrower who currently has the Guinness World Record for the world's longest throw of anything without a tail. 427.2m
For any of the flitetest guys we are happy to have you collect loose sheets and also pack up 5 sheets for you to either collect or arrange for your own courier to collect. Aussie Post is not great for the larger sheets as they exceed their current size restrictions.
I'm not here for self promotion as most of our business is to large multi-nationals and it is only because of my passion or hobby for building boomerangs and other flying toys that I started to break up cartons of foam board for people to use in smaller quantities.
Hopefully as we move forward we can start to produce some revolutionary products locally for the Aussie domestic market that compete favourably on both price and features.
If you need any help, advice or samples...even long thin off cut packs that might suit, please let me know.
I'm not always on the forum but will check in from time to time.
I just wanted to put a personal face to the solutions that are available in Australia.
best regards,
