I'm not claiming to be an expert, but I have done these bureaucratic things a few times, and here's a few observations and questions.
Firstly, is it right that the club can have property and powers (S. 3 & 4). Not being incorporated, i don't think they can. Actually even when incorporated, I think the power has to rest with the office bearers.
7 - expulsion - this can be tricky. Firstly, maybe the formatting on the google doc is screwed, but put the failure to pay dues before expulsion, keep the relevant bits with each other. Secondly, need to clear up voting procedure for expulsion.
Voting for executive positions needs to be clearer, put it in 8.1
You don't need to spell out the jobs in that much detail. I wouldn't make door manager an executive role.
Don't put the AGM agenda in the constitution, that's just odd.
general meetings to be in writing? how about posted online in a generally accepted place (e.g. this board)? In fact, the website doesn't get a mention and it should - maybe an office bearer?
The Minutes should be required to be generally available - e.g. on this board. In fact you really need to embed this board into the processes generally I reckon.
For dissolution/winding up, that doesn't allow for the auctioning of items and donating proceeds to a charity. i don't think the Red Cross want W40K terrain!
