And finally - think about your request for 5500'. What height do all of the YMML SIDs finish at? What is the minimum clearance between IFR and VFR required to be provided in Class C?
Can you find the 500' problem?
Admittedly it was a long time ago since I tried it VFR but I've never ever been refused a clearance over Melbourne at 6000'.
Requesting VFR levels through Class C probably gets you labeled 'numpty' on first contact and far less likely to get you a favorable hearing.
