There are no stages as such.
A site is suggested, an editor reviews it, and does 1 of 4 things
Lists it (either in the category it was suggested to, or another category if they have permissions in that other category)
Moves it (usually to a category closer to where it will be listed based on the site information)
Deletes it (usually for lack of unique content)
Does nothing and leaves it for later or another editor (this can occur for several reasons - browser crash, real life interruptions, telstra drops out after 10 hours
, unable to spend sufficient time to understand a site) [These are all real examples from my last couple of weeks]
Next time an editor looks at the site the exact same 4 things could occur again.
We are unable to determine when next an editor will look at the site, so cannot predict if and/or when a particular site may be reviewed. I'd be surprised if any sites in Australia have more than a 2 year wait, but it can, and does, occur in some categories. Of course it may have been reviewed while I typed this. Just never can tell.
