|Good suggestions upthread, and excellent work on the podcast so far.
Keith Bell is a legend and will talk well, did some significant ascents in America in the 70s too (e.g. The Nose in 30hrs or so with Henry Barber prior to the "first one day ascent", and I think the second ascent of 3rd pillar of Dana with Galen Rowell).
Fantini is back in the country, living history right there.
I'm not that interested in "nice friendly crushers". Oddballs, grumpy old misanthropes, and other original thinkers make for better listening. Other suggestions from Canberra are;
John Smart, who was putting up routes in the ACT in the late 70s which were on par with the cutting edge stuff at Araps. He also did some hard stuff in Tassie and the first ascent of Downwind of Angels.
Roark Muhlen, who had a real eye for hard bold lines in the early 80s (kind of equivalent to things like Open Season and Delirium Tremens), and is involved in the GAWG (if you want to open that can of worms).
Tony Barten, put up a huge number of really great hard routes from the mid 80s through to the mid 90s, went on overseas epic adventures, has a great sense of humour and would hopefully rip into various aspects of Australian climbing in a hilarious way.
Mike Peck, a bit of a low key character who also put up tons of great routes in the 80s, edited two editions each of ACT and Point Perp guidebooks, was involved in the amazing climbing mag Gripped Off Me Scone. His contribution to climbing over a decade was equal to peak Neil Monteith manic output.
Also; Wendy and Ester from Nati, Scott Camps or Squeak from Girraween, Roger Parkyn from Tassie
