Good move cobba
Mrs & I too departed the 'vile some years ago for Van Diemens Land and the best move we've made.
The GA scene is pretty much monopolised by PAFT in Hobart, they also own the airport (YCBG). ACST are still going but PAFT to their checking I think.
NO Ultra light options here I'm afraid but some out of Devonport.
PAFT are very professional with a real Gent of a CFI goes by the name of Ralph, look him up for a chat when you get into town.
There are some options in the North for GA, Evandale (YLST) and Wynyard I think but just depends how much driving you want to do.
Not sure what you are paying to hire a C172 out of YBTL these days ($120.00 /hr solo when I last hired there, circa 2001) but prices are a bit hexy down here (North of $300.00 dual these days) Sign of the times I guess
PM me if you like when you hit town, I might be looking for someone to play with once I sort my BFR out. Have to fund it myself these days
Cheers BAz
PS the farm strip you refer to the The Vale, 1.2 Km nicely maintained grass.
Can't wait to check it out myself some day
