First, the bicycles in the team pursuit picture with Ken Evans stickers on were not made by Ken Evans, he merely paid for the right to advertise. The frames were made by Bryan Hayes (the maker of Euro frames). Hayes also made Europa frames from the late 1970s to 1984 and put some Europa stickers on later models up to 1989.

That picture is not taken at the 1984 Olympics, it is from about 1988 and it's not from an Olympics. Lead rider looks like Brett Dutton, second is Scott McGrory, third is Dean Woods. I would hazard a guess that the final rider is Darren Winter.

From memory, the handlebars used on those bikes were 3T (or 'ttt' as they were marked back then).

Bryan Hayes now works with Sal Sansonetti on BT frames.

Deathhare, Australian track frames are fairly easy to get hold of because in Australia the road season grinds to a halt in mid-summer (except for the Tour Down Under) - which means if you want to race all year round you need a track bike.

This guy has some fine old Australian track bikes for sale - mostly South Australian brands - Super Elliot, Christophe and the entry-level Macini. www.collectablecycles.com

Pics of my old but much loved (and raced) 1986 Euro here http://tvvas.blogspot.com/2007/04/my-bike.html#links now used for riding to work in Tokyo. Gets a few couriers scratching their heads when they see the stickers.
