It might take a while to get used to a short wheel base recumbent. A lady I rode with Saturday said it took her 4 months to get used to hers, but she goes everywhere on it now. For me, it was mostly an issue of balance, and the seat not letting me put a foot down easily. The seat in the picture you posted should be better than the one I had.
You might also go to bentrideronline.com and ask this question. I believe there's someone on there from Adelaide.
