Great question! D you know???
No, not just for people in Melbourne...
With cloud overcast at 3,100’ - what’s the highest altitude you can fly over Avalon under the VFR?

I suspect you are wondering if it's 2,100ft or 3,000 ft.... But class E only goes to 2,500ft.
You have asked a trick question, as you didn't specify under or over the cloud so in fact, the answer would be as high as I am allowed in Class C airspace subject to the limitations of my aircraft and equipment as I could very well be VFR over the top at even 8,000+ or more for example.
You also didn't say OCTA or not so of you intended to fly through VFR OCTA with 3,100 overcast you might be out of luck.... Is that what you are thinking?

It's been a while since I've flown down that way, but looking at a VTC that I have, Avalon is class D from SFC to 2500, and class E 2500 to 4500.
Class D requires you to be 500 ft below cloud; Class E requires 1000 ft vertical separation. So if you're in E, the highest you can be is 2100 ft but at 2100 ft, you're in D, so that means you only need to be 500 ft below cloud. So if the cloud base is 3100 ft, 500 ft below the cloud base means you can be at 2600 ft but that puts you in E and in E, you need 1000 ft vertical separation from cloud.
So I guess that's why you're asking because there is no clear answer! Good one!

At 2500' you're in class E and require 1000' above.
The answer to the question is 2500', unless VFR on top.

If the D/E vertical boundary is 2500, and you're cruising at 2500, you're in E.
At vertical boundaries, you are in the "lesser" class of airspace, reference is AIP ENR 1.4-2 Para 1.1.7

I stand corrected.
AIP ENR 1.4-2 para 1.1.7:
AIP ENR 1.4-2 para 1.1.7:
When ATS airspaces adjoin vertically (one above the other), flights at the common level must comply with the requirements of, and will be given services applicable to, the less restrictive class of airspace. ...

Cloud clearance?
When in E and VFR below 3000 AMSL, do you not simply need to be clear of cloud and have surface (ground or water) in sight?
So as far as the OP's question goes, my answer would have been therefore (technically) to transit at 3000ft if wishing to remain OCTA. BUT I would be inclined to remain at 2500 to ensure less winkage if old mate in his light twin kero burner suddenly dropped out of said cloud.

So is the answer 3,000ft ?

Do flyers realise that at Avalon, the D (Tower) airspace IS NOT controlled by the tower! When the tower is open, they do not own any airspace!
Nomde plume had it in post 3. 2499 if the tower is active. Probably 2400 effectively or a 'not above 2500' clearance flying at just under 2500.
2100 if the tower is inactive and E goes down to 700.

Ahhhhhhhh yuk me head hurts
Just don't fly into the cloud or kill yourself and you'll be fine....... ( yes by definition I guess )
