That's a routing issue more than a protocol issue.
Simply have your default routers at each site point across the frame relay
link for the specified destination IP addresses rather than spraying it
out into the internet.
I'd be more concerned, if I were you, at the possibility of a
core-critical application being accessable from the internet! If I
understand you correctly, users in Sydney would telnet out through the
internet link in Sydney, and then come back in through the internet link
in Melbourne? This is a recipie for disaster, speaking from a security
point of view!
