Bank of Melb - $10 for up to 4 cheques negotiated in the same currency (immediate conversion and clearance), but they can be anal about anything larger than chicken feed. I'm a regular there so I don't have (m)any problems now. I usually wait and deposit 4 at a time so effectively they cost $2.50 each.
If you're outside of Victoria, BoM are owned by Westpac, they may offer the same deal.
Otherwise it's $35 for collection, up to 4 cheques and around 6 weeks clearance.
CBA were doing o/s cheques for $7 last time I banked there, they'll negotiate anything up to $5000 and will place a 28 day hold on the funds. I only used CBA until BoM stopped being anal.
